If a standard pinout is required, use the KM4170. The KM7101 uses only 136µA of supply current and offers no crossover distortion. The input common mode voltage range exceeds the negative and positive rails. The KM7101 offers high bipolar performance at a low CMOS price. The KM7101 offers superior dynamic performance with a 4.9MHz small signal bandwidth and 5.3V/µs slew rate. The combination of low power, high bandwidth, and rail-to-rail performance make the KM7101 well suited for batterypowered communication/computing systems.
