3 Description

The THS3091 and THS3095 are high-voltage, lowdistortion,

high-speed, current-feedback amplifiers

designed to operate over a wide supply range of

±5 V to ±15 V for applications requiring large, linear

output signals such as pin drivers, power FET drivers

& arbitrary waveform generators.

The THS3095 features a power-down pin (PD) that

puts the amplifier in low power standby mode, and

lowers the quiescent current from 9.5 mA to 500 μA.

The wide supply range, combined with total harmonic

distortion as low as –69 dBc at 10 MHz, in addition

to the high slew rate of 7300 V/μs makes the

THS309x ideally suited for high-voltage arbitrary

waveform driver applications. Moreover, having the

ability to handle large voltage swings driving into

high-resistance and high-capacitance loads while

maintaining good settling time performance makes the

devices ideal for Pin driver and Power FET driver

applications.

The THS3091 and THS3095 are offered in an 8-pin

SOIC (D), and the 8-pin SOIC (DDA) packages with

PowerPAD?. The THS3091 is also offered in an

additional 8-pin HVSSOP (DGN) package.
