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 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. Heavy loads up to ±250 mA can be driven by high-frequency large signals with the LMH6629’s –3dB bandwidth of 900 MHz and 1600 V/µs slew rate. The LMH6629 (WSON-8 package only) 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. Compensation 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 nV/√Hz and 2.6 pA/√Hz), low distortion (HD2/HD3 = −90 dBc/−94 dBc) 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 SiGe process and is available in a 3 mm × 3 mm 8-pin WSON package as well as the SOT-23-5 package.
