3 Description

The THS3091 and THS3095 (THS309x) are highvoltage,

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 slewrate,

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.
