DESCRIPTION
The THS3092 and THS3096 are dual high-voltage,
low-distortion, 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, Power FET,
and VDSL line drivers.
The THS3096 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 -66 dBc at 10 MHz, in addition, to
the high slew rate of 5700 V/µs makes the
THS3092/6 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 THS3092/6 ideal for Pin driver and PowerFET
driver applications.
The THS3092 is offered in an 8-pin SOIC (D), and
the 8-pin SOIC (DDA) packages with PowerPAD™.
The THS3096 is offered in the 8-pin SOIC (D) and
the 14-pin TSSOP (PWP) packages with PowerPAD.
