Advance Data Sheet
Application Information
General Description
The CLC1010 family are a single supply, general purpose,
voltage-feedback amplifiers fabricated on a complementary
bipolar process. The CLC1010 offers 7.3MHz unity gain
bandwidth, 9V/μs slew rate, and only 70μA supply current.
It features a rail-to-rail output stage and is unity gain stable.
The design utilizes a patent pending topology that provides
increased slew rate performance. The common mode input
range extends to 300mV below ground and to 1.2V below
Vs. Exceeding these values will not cause phase reversal.
However, if the input voltage exceeds the rails by more
than 0.5V, the input ESD devices will begin to conduct. The
output will stay at the rail during this overdrive condition.
The design uses a Darlington output stage. The output
stage is short circuit protected and offers “soft” saturation
protection that improves recovery time.
Figures 1, 2, and 3 illustrate typical circuit configurations for
non-inverting, inverting, and unity gain topologies for dual
supply applications. They show the recommended bypass
capacitor values and overall closed loop gain equations.
Figure 4 shows the typical non-inverting gain circuit for
single supply applicaitons.
