The THS3091 and THS3095 (THS309x) are high-voltage, low-distortion, high-speed, current-feedback amplifiers that operate over a wide supply range of ±5 V to ±16 V. These devices are an excellent choice for applications that require large, linear output signals, such as pin drivers, power-FET drivers, and arbitrary waveform generators.

The THS3095 features a power-down pin ( PD) that puts the amplifier into a low-power standby mode, and lowers the quiescent current from 9.5 mA to 500 µA.

The wide, 32‑V supply range, 6000‑V/µs slew-rate, and 310‑mA output current drive make the THS309x an excellent choice for high-voltage arbitrary-waveform-driver applications. Moreover, with the ability to handle large voltage swings driving into low-resistance and high-capacitance loads while maintaining good settling time performance, these devices are an excellent choice for pin-driver and power-FET driver applications.

The THS309x are offered in an 8‑pin SOIC (DDA) PowerPAD™ integrated circuit package. The THS3091 is also offered in an 8‑pin HVSSOP (DGN) package.
