Gain ≥4 or ≥10 V/V Enable Time: 75 ns Output Current ±250 mA WSON-8 and SOT-23-5 Packages 2 Applications Instrumentation Amplifiers Ultrasound Pre-amps Wide-band Active Filters Opto-Electronics Medical Imaging Systems Base-Station Amplifiers Low-Noise Single Ended to Differential Conversion Trans-Impedance Amplifier 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 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 highfrequency large signals with the LMH6629's –3dB bandwidth of 900 MHz and 1600 V/µs...
