HIGH-VOLTAGE, LOW-DISTORTION, CURRENT-FEEDBACK

OPERATIONAL AMPLIFIERS

• Low Distortion

The THS3091 and THS3095 are high-voltage,

low-distortion, high-speed, current-feedback

– 77 dBc HD2 at 10 MHz, R

= 1 k Ω

amplifiers designed to operate over a wide supply

– 69 dBc HD3 at 10 MHz, R

= 1 k Ω

range of ± 5 V to ± 15 V for applications requiring

• Low Noise

large, linear output signals such as Pin, Power FET,

– 14 pA/ √ Hz Noninverting Current Noise and VDSL line drivers.

– 17 pA/ √ Hz Inverting Current Noise

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

puts the amplifier in low power standby mode, and

– 2 nV/ √ Hz Voltage Noise

lowers the quiescent current from 9.5 mA to 500 µ A.

• High Slew Rate: 7300 V/ µ s (G = 5, V

= 20 V

)

The wide supply range combined with total harmonic

• Wide Bandwidth: 210 MHz (G = 2, R

= 100 Ω )

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

• High Output Current Drive: ± 250 mA

to the high slew rate of 7300 V/ µ s makes the

• Wide Supply Range: ± 5 V to ± 15 V

THS3091/5 ideally suited for high-voltage arbitrary

waveform driver applications. Moreover, having the

• Power-Down Feature: (THS3095 Only)

ability to handle large voltage swings driving into

high-resistance and high-capacitance loads while

maintaining good settling time performance makes

• High-Voltage Arbitrary Waveform

the devices ideal for Pin driver and PowerFET driver

• Power FET Driver

applications.

• Pin Driver

The THS3091 and THS3095 are offered in an 8-pin

• VDSL Line Driver
