THS4032 - 100-MHz Low Noise Voltage-Feedback Amplifier, Dual

The THS4031 and THS4032 are ultra-low voltage noise, high-speed voltage feedbackamplifiers that are ideal for applications requiring low voltage noise, including communicationsand imaging. The single amplifier THS4031 and the dual amplifier THS4032 offer good AC performancewith 100-MHz bandwidth (G = 2), 100-V/µs slew rate, and 60-ns settling time (0.1%). The THS4031 andTHS4032 are unity-gain stable with 275-MHz bandwidth. These amplifiers have a high drive capabilityof 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, the THS4031 andTHS4032 are designed for applications requiring low distortion and low noise such as bufferinganalog-to-digital converters.
