Overview
The THS4032IDR, produced by Texas Instruments, is a dual-amplifier version of the THS403x series. These amplifiers are ultra-low voltage noise, high-speed voltage feedback amplifiers, making them an excellent choice for applications requiring low voltage noise, such as communications and imaging.
The THS4032 offers very good ac performance with a 100MHz bandwidth (G = 2), a 100V/µs slew rate, and a 70ns settling time (0.1%). These amplifiers are unity-gain stable with a 120MHz bandwidth and have a high drive capability of 200mA while drawing only 7.5mA supply current per channel.
