LOW-NOISE, HIGH-VOLTAGE, CURRENT-FEEDBACK,

OPERATIONAL AMPLIFIERS

•

Low Noise

The

THS3110

and

THS3111

are

low-noise,

high-voltage, current-feedback amplifiers designed to

– 2 pA/

√Hz Noninverting Current Noise

operate over a wide supply range of

±5 V to ±15 V for

– 10 pA/

√Hz Inverting Current Noise

today's high performance applications.

– 3 nV/

√Hz Voltage Noise

The THS3110 features a power-down pin (PD) that

•

High Output Current Drive: 260 mA

puts the amplifier in low power standby mode, and

•

lowers the quiescent current from 4.8 mA to 270 µA.

These

amplifiers

bandwidth of 100 MHz allows for good distortion

characteristics below 10 MHz. Coupled with high

•

Power-Down Feature: (THS3110 Only)

1300-V/µs slew rate, the THS3110 and THS3111

amplifiers allow for high output voltage swings at high

frequencies.

•

Video Distribution

The THS3110 and THS3111 are offered in a 8-pin
