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.
