CLC5802
Dual Low-Noise, Voltage Feedback Op Amp
General Description
The CLC5802 is a dual op amp that offers a traditional
voltage-feedback topology featuring unity-gain stability. Low
noise and very low harmonic distortion combine to form a
very wide dynamic-range op amp that operates within a
power supply range of 5V to 12V.
Each of the CLC5802's closely matched channels provides a
140MHz unity-gain bandwidth with a very low input voltage
noise density (4nV/
). Low 2nd/3rd harmonic distortion
(-69/-66dBc) as well as high channel-to-channel isolation
(-61dB) make the CLC5802 a perfect wide dynamic-range
amplifier for I/Q channels and other application which require
low distortion and matching. With its fast and accurate set-
tling (18ns to 0.1%), the CLC5802 is also a excellent choice
for wide-dynamic range, anti-aliasing filters to buffer the in-
puts of hi-resolution analog-to-digital converters. Combining
the CLC5802 two tightly-matched amplifiers in a single
eight-pin SOIC reduces cost and board space for many com-
posite amplifier applications such as active filters, differential
line drivers/receivers, fast peak detectors and instrumenta-
tion amplifiers.

Note 1: "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The table of "Electrical Characteristics" specifies conditions of device operation. Operating Ratings indicate conditions for which
the device is intended to be functional, but specific performance is not guaranteed,
Note 2: Min/max ratings are based on product characterization and simulation. Individual parameters are tested as noted. Outgoing quality levels are determined
from tested parameters.
Note 3: Output is short circuit protected to ground, however maximum reliability is obtained if output current does not exceed 160mA.
Note 4: 100% tested at +25C.
