DATA ACQUISITION
DESCRIPTION
The OPA743 series utilizes a state-of-the-art 12V analog
CMOS process and offers outstanding AC performance,
such as 7MHz GBW, 10V/
s slew rate and 0.0008% THD+N.
Optimized for single supply operation up to 12V, the input
common-mode range extends beyond the power supply rails
and the output swings to within 100mV of the rails. The low
quiescent current of 1.1mA makes it well suited for use in
battery operated equipment.
The OPA743 series' ability to drive high output currents
together with 12V operation makes it particularly useful for
use as gamma correction reference buffer in LCD panels.
For ease of use the OPA743 op-amp family is fully specified
and tested over the supply range of
1.75V to
6V. Single,
dual and quad versions are available.
The single versions (OPA743) are available in the MicroSIZE
SOT23-5 and in the standard SO-8 surface-mount, as well as
DIP-8 packages. Dual versions (OPA2743) are available ver-
sions in the MSOP-8, SO-8, and DIP-8 packages. The quad
versions (OPA4743) are available in the TSSOP-14 and SO-14
packages. All are specified for operation from 40
C to +85
C.

NOTES: (1) Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods may degrade
device reliability. (2) Input terminals are diode-clamped to the power supply
rails. Input signals that can swing more than 0.3V beyond the supply rails
should be current-limited to 10mA or less. (3) Short-circuit to ground, one
amplifier per package.
ABSOLUTE MAXIMUM RATINGS

ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instru-
ments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degrada-
tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.

APPLICATIONS INFORMATION
OPA743 series op amps can operate on 1.1mA quiescent
current from a single (or split) supply in the range of 3.5V
to 12V (
1.75V to
6V), making them highly versatile and
easy to use. The OPA743 is unity-gain stable and offers
7MHz bandwidth and 10V/
s slew rate.
Rail-to-rail input and output swing helps maintain dynamic
range, especially in low supply applications. Figure 1 shows
the input and output waveforms for the OPA743 in unity-
gain configuration. On a
6V supply with a 100k
load
connected to V
S
/2. The output is tested to swing within
100mV to the rail.
Power-supply pins should be bypassed with 1000pF ceramic
capacitors in parallel with 1
F tantalum capacitors.
OPERATING VOLTAGE
OPA743 series op amps are fully specified and guaranteed
from 3.5V to 12V over a temperature range of 40C to
+85C. Parameters that vary significantly with operating
voltages or temperature are shown in the Typical Character-
istics.
RAIL-TO-RAIL INPUT
The input common-mode voltage range of the OPA743 series
extends 100mV beyond the supply rails at room temperature.
This is achieved with a complementary input stage--an N-
channel input differential pair in parallel with a P-channel
differential pair. The N-channel pair is active for input volt-
ages close to the positive rail, typically (V+) 2.0V to 100mV
above the positive supply, while the P-channel pair is on for
inputs from 100mV below the negative supply to approxi-
mately (V+) 1.5V. There is a small transition region,
typically (V+) 2.0V to (V+) 1.5V, in which both pairs are
on. This 500mV transition region can vary
100mV with
process variation. Thus, the transition region (both stages on)
can range from (V+) 2.1V to (V+) 1.4V on the low end,
up to (V+) 1.9V to (V+) 1.6V on the high end. Most rail-
to-rail op amps on the market use this two input stage
approach, and exhibit a transition region where CMRR, offset
voltage, and THD may vary compared to operation outside
this region.

INPUT VOLTAGE
Device inputs are protected by ESD diodes that will conduct if
the input voltages exceed the power supplies by more than
approximately 300mV. Momentary voltages greater than 300mV
beyond the power supply can be tolerated if the current is limited
to 10mA. This is easily accomplished with an input resistor, in
series with the op amp input as shown in Figure 2. Many input
signals are inherently current-limited to less than 10mA; there-
fore, a limiting resistor is not always required. The OPA743
features no phase inversion when the inputs extend beyond
supplies if the input current is limited, as seen in Figure 3.

RAIL-TO-RAIL OUTPUT
A class AB output stage with common-source transistors is
used to achieve rail-to-rail output. This output stage is
capable of driving 1k
loads connected to any point be-
tween V+ and V. For light resistive loads (> 100k
), the
output voltage can swing to 100mV from the supply rail.
With 1k
resistive loads, the output can swing to within
325mV from the supply rails while maintaining high open-
loop gain (see the typical performance curve "Output Volt-
age Swing vs Output Current").

CAPACITIVE LOAD AND STABILITY
The OPA743 series op amps can drive up to 1000pF pure
capacitive load. Increasing the gain enhances the amplifier's
ability to drive greater capacitive loads (see the typical
performance curve "Small Signal Overshoot vs Capacitive
Load").
One method of improving capacitive load drive in the unity-
gain configuration is to insert a 10
to 20
resistor inside
the feedback loop, as shown in Figure 4. This reduces
ringing with large capacitive loads while maintaining DC
accuracy.
APPLICATION CIRCUITS
The OPA743 series op amps are optimized for driving
medium-speed sampling data converters. The OPA743 op
amps buffer the converter's input capacitance and resulting
charge injection while providing signal gain.
Figure 5 shows the OPA743 in a dual supply buffered
reference configuration for the DAC7644.
REFERENCE BUFFER FOR LCD SOURCE DRIVERS
In modern high resolution TFT LCD displays, gamma cor-
rection must be performed to correct for nonlinearities in the
glass transmission characteristics of the LCD panel. The
typical LCD source driver for 64 Bits of Grayscale uses
internal DAC to convert the 6-Bit data into analog voltages
applied to the LCD. These DAC typically require external
voltage references for proper operation. Normally these ex-
ternal reference voltages are generated using a simple resis-
tive ladder, like the one shown in Figure 6.
Typical laptop or desktop LCD panels require 6 to 8 of the
source driver circuits in parallel to drive all columns of the
panel. Although the resistive load of one internal string DAC
is only around 10k
, 6 to 8 in parallel represent a very
substantial load. The power supply used for the LCD source
drivers for laptops is typically in the order of 10V. To
maximize the dynamic range of the DAC, rail-to-rail output
performance is required for the upper and lower buffer. The
OPA4743's ability to operate on 12V supplies, to drive
heavy resistive loads (as low as 1k
), and to swing to within
325mV of the supply rails, makes it very well suited as a
buffer for the reference voltage inputs of LCD source drivers.
During conversion, the DAC's internal switches create cur-
rent glitches on the output of the reference buffer. The
capacitor C
L
(typically 100nF) functions as a charge reser-
voir that provides/absorbs most of the glitch energy. The
series resistor R
S
isolates the outputs of the OPA4743 from
the heavy capacitive load and helps to improve settling time.
