The Texas Instruments THS4032 series device are ultra-low voltage noise, high-speed voltage feedback amplifiers that are ideal for applications requiring low voltage noise, including communications and imaging. The single amplifier and the dual amplifier offer good AC performance with 100-MHz bandwidth (G = 2), 100-V/μs slew rate, and 60-ns settling time (0.1%). The amplifiers are unity-gain stable with 275-MHz bandwidth. These amplifiers have a high drive capability of 90 mA and draw only 8.5-mA supply current per channel. With –90 dBc of total harmonic distortion(THD) at f = 1 MHz and a very low noise of 1.6 nV/√Hz, these are designed for applications requiring low distortion and low noise such as buffering analog-to-digital converters.
