LMH6629 Datasheet High Speed Operational Amplifier

Manufacturer: National Semiconductor Corporation

Overview: www.DataSheet4U.com LMH6629 Ultra-Low Noise, High Speed Operational Amplifier June 3, 2010 LMH6629 Ultra-Low Noise, High Speed Operational.

General Description

The LMH6629 is a high speed, ultra low-noise amplifier designed for applications requiring wide bandwidth with high gain and low noise such as in communication, test and measurement, optical and ultrasound systems.

The LMH6629 operates on 2.7 to 5.5V supply with an input common mode range that extends below ground and outputs that swing to within 0.8V of the rails for ease of use in single supply applications.

The LMH6629 has user-selectable internal compensation for minimum gains of 4 or 10 controlled by pulling the COMP pin low or high, thereby avoiding the need for external compensation capacitors required in competitive devices.
