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°.
