Overview
The THS3092, specifically the THS3092DDAG4, is a dual high-voltage, low-distortion, high-speed current-feedback operational amplifier produced by Texas Instruments. This amplifier is designed to operate over a wide supply range of ±5 V to ±15 V, making it suitable for applications requiring large, linear output signals. The THS3092 is particularly ideal for high-voltage arbitrary waveform driver applications, as well as for driving power FETs, pins, and VDSL lines due to its high slew rate and low distortion characteristics.
