LMH6629
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 munication, test and measurement, optical and ultrasound systems. The LMH6629 operates on 2.7 to 5.5V supply with an input mon 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 pensation for minimum gains of 4 or 10 controlled by pulling the P pin low or high, thereby avoiding the need for external pensation capacitors required in petitive devices. The low-input noise (0.69n V/√Hz and 2.6 p A/√Hz), low distortion (HD2/ HD3 =
- 90 d Bc/
- 94 d Bc) and ultra-low DC errors (780 µV VOS Max @ 25°C, ±0.45 µV/°C drift) allow precision operation in both AC- and DC-coupled applications. The LMH6629 is fabricated in National Semiconductor’s proprietary Si Ge process and is available in a 3mm x 3mm, 8 pin LLP...
