The KM4100 (single) and KM4101 (single with disable) are low cost, voltage feedback amplifiers. These amplifiers are 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 KM4100 offers superior dynamic performance with a 260MHz small signal bandwidth and 150V/µs slew rate. The combination of low power, high output current drive, and rail-to-rail performance make the KM4100 well suited for battery-powered communication/computing systems. The combination of low cost and high performance make the KM4100 suitable for high volume applications in both consumer and industrial applications such as wireless phones, scanners, etc.
The KM4100 and KM4101 are single-supply, general-purpose voltage-feedback amplifiers fabricated on a complementary bipolar process. They feature a rail-to-rail output stage and are unity gain stable, designed to operate on +2.7V or +5V supplies.
These devices offer superior dynamic performance with a 260MHz small signal bandwidth and 150V/us slew rate. The KM4101 includes an active-low disable pin that reduces supply current to below 127µA when disabled, making them suitable for battery-powered applications.
