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 VOS 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.
