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.
