3 Description
The THS3091 and THS3095 are high-voltage, low-
distortion, high-speed, current-feedback amplifier
designed to operate over a wide supply range of ±5 V
to ±15 V for applications requiring large, linear output
signals such as Pin, Power FET, and VDSL line
drivers.
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™.
