Overview
The THS3092, produced by Texas Instruments, is a dual high-voltage, low-distortion, high-speed current-feedback operational amplifier. It is designed to operate over a wide supply range of ±5 V to ±15 V, making it suitable for applications that require large, linear output signals. The THS3092 is particularly ideal for high-voltage arbitrary waveform driver applications, Pin drivers, Power FET drivers, and VDSL line drivers due to its low distortion, high slew rate, and wide bandwidth.
