KM4121IT6 0.2mA, Low Cost, +2.7V & +5V, 35MHz Rail-to-Rail Amplifiers

General Description
The KM4111 (single) and KM4121 (single with disable) are ultra-low power, low cost, voltage feedback amplifiers. These amplifiers use only 208µA of supply current and 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 KM4111 offers high bipolar performance at a low CMOS price. The KM4111 offers superior dynamic performance with a 35MHz small signal bandwidth and 27V/µs slew rate. The combination of lowpower, high bandwidth, and rail-to-rail performance make the KM4111 well suited for battery-powered communication/computing systems.

Features
■ 208µA supply current
■ 35MHz bandwidth
■ Power down to Is = 35µA (KM4121)
■ Fully specified at +2.7V and +5V supplies
■ Output voltage range: 0.08V to 4.88V; Vs = +5
■ Input voltage range: -0.3V to +3.8V; Vs = +5
■ 27V/µs slew rate
■ ±8.5mA linear output current
■ ±13mA short circuit output current
■ 21nV/√Hz input voltage noise
■ Directly replaces MAX4281
■ Small package options (SOT23-5 and SOT23-6)

Applications
■ Portable/battery-powered applications
■ A/D buffer
■ Active filters
■ Signal conditioning
■ Portable test instruments
