3 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-V to 5.5-V supply with an input mon 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. Heavy loads up to ±250 m A can be driven by highfrequency large signals with the LMH6629's
- 3d B bandwidth of 900 MHz and 1600 V/µs slew rate. The LMH6629 (WSON-8 package only) has userselectable 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. pensation for the SOT-23-5 package is internally set for a minimum stable gain of 10 V/V. The WSON-8 package also provides the power-down enable/disable feature
.
The low-input noise (0.69 n V/√Hz and 2.6 p A/√Hz), low distortion (HD2/HD3 =
- 90 d Bc/- 94 d Bc) and ultra-low DC errors (800 µV VOS maximum over temperature, ±0.45 µV/°C drift) allow precision operation in both ac- and dc-coupled applications.
The LMH6629 is fabricated in Texas Instruments' proprietary Si Ge process...
