EL5127, EL5227, EL5327, EL5427
2.5MHz 4, 8, 10 & 12 Channel Rail-to-Rail
Buffers
The EL5127, EL5227, EL5327, and EL5427 are low power,
high voltage rail-to-rail input/output buffers designed for use
in reference voltage buffering applications in small LCD
displays. They are available in quad (EL5127), octal
(EL5227), 10-channel (EL5327), and 12-channel (EL5427)
topologies. All buffers feature a -3dB bandwidth of 2.5MHz
and operate from just 133A per buffer. This family also
features a continuous output drive capability of 30mA (sink
and source).
The quad channel EL5127 is available in the 10-pin MSOP
package. The 8-channel EL5227 is available in both the 20-
pin TSSOP and 24-pin QFN packages, the 10-channel
EL5327 in the 24-pin TSSOP and 24-pin QFN packages,
and the 12-channel EL5427 in the 28-pin TSSOP and 32-pin
QFN packages. All buffers are specified for operation over
the full -40C to +85C temperature range.
Features
2.5MHz -3dB bandwidth
Supply voltage = 4.5V to 16.5V
Low supply current (per buffer) = 133A
High slew rate = 2.2V/s
Rail-to-rail input/output swing
Ultra-small packages
Pb-free plus anneal available (RoHS compliant)
Applications
TFT-LCD drive circuits
Electronic games
Touch-screen displays
Personal communication devices
