The KM4212 is an ultra-low power, low cost, voltage feedback amplifier. The KM4212 uses only 70A of supply current and is designed to operate on +2.7V, +5V, or ±2.5V supplies. The input voltage range extends 300mV below the negative rail and 1.2V below the positive rail.
The KM4212 offers high bipolar performance at a low CMOS price. The KM4212 offers superior dynamic performance with a 7.3MHz small signal bandwidth and 9V/s slew rate. The combination of low power,high bandwidth, and rail-to-rail performance make the KM4212 well suited for battery-powered commu-nication/computing systems.
The KM4112 single amplifier is also available.
The KM4212 is a single supply, general purpose, voltage-feedback amplifier fabricated on a complementary bipolarprocess. The KM4212 offers 7.3MHz unity gain bandwidth, 9V/s slew rate, and only 70A 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 out-put stage is short circuit protected and offers "soft"saturation protection thatimproves recovery time.
The typical circuit schematic is shown in Figure 1.
