LMH6629 Ultra-Low Noise High Speed Op Amp

Texas Instruments' operational amplifier for applications requiring wide bandwidth with high gain and low noise

image of Texas Instruments' LMH6629 Ultra-Low Noise, High Speed Op AmpNational Semiconductor's 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 V to 5.5 V supply with an input common mode range that extends below ground and outputs that swing to within 0.8 V 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.

The low-input noise (0.69 nV/ √Hz and 2.6 pA/ √Hz), low distortion (HD2/ HD3 = -90 dBc/ -94 dBc), and ultra-low DC errors (780 µV VOS max @ 25°C, ±0.45µV/°C drift) allow precision operation in both AC- and DC-coupled applications.
