CLC1003
Low Distortion, Low Offset, RRIO Amplifier
General Description
The CLC1003 is a single channel, high-performance, voltage feedback
amplifier with near precision performance, low input voltage noise, and
ultra low distortion. The CLC1003 offers 1mV maximum input offset voltage,
3.5nV/√Hz broadband input voltage noise, and 0.00005% THD at 1kHz.
These amplifiers also provide 55MHz gain bandwidth product and 12V/μs
slew rate making them well suited for applications requiring precision DC
performance and high AC performance. This high-performance amplifier
also offers a rail-to-rail input and output, simplifying single supply designs
and offering larger dynamic range possibilities. The inputs extend beyond
the rails by 500mV.
The CLC1003 is designed to operate from 2.5V to 12V supplies and
operate over the extended temperature range of -40°C to +125°.
