The THS3491 is a high-voltage, low-distortion, high-speed, current-feedback amplifier designed to operate over a wide supply range of ±7 V to ±16 V for applications requiring large, linear output swings such as arbitrary waveform generators.

The THS3491 features a power-down pin that puts the amplifier in low power standby mode and lowers the quiescent current from 16.7 mA to 750 µA.

The RGT package also features a feedback pin (pin 1). Internally on the die this pin is connected to the amplifier's output. This feedback pin arrangement minimizes the PCB trace lengths in the feedback path for the connection from the feedback resistor to the inverting input and output pins. This in turn minimizes the board parasitics in the feedback path, thus allowing to maximize bandwidth with minimal peaking.
