LMH6629

June 3, 2010

Ultra-Low Noise, High Speed Operational Amplifier

General Description

The LMH6629 is a high speed, ultra low-noise amplifier de-

signed for applications requiring wide bandwidth with high

gain and low noise such as in communication, test and mea-

surement, 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 inter-

nal 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.

The low-input noise (0.69nV/

√Hz and 2.6 pA/√Hz), low dis-

tortion (HD2/ HD3 = −90 dBc/ −94 dBc) and ultra-low DC

errors (780 µV V

OS Max @ 25°C, ±0.45 µV/°C drift) allow pre-

cision operation in both AC- and DC-coupled applications.

The LMH6629 is fabricated in National Semiconductor’s pro-

prietary SiGe process and is available in a 3mm x 3mm, 8 pin

LLP package.
