FEATURES

DESCRIPTION

•

Low Noise

The THS3110 and THS3111 are low-noise,

high-voltage, current-feedback amplifiers designed to

operate over a wide supply range of ±5 V to ±15 V for

today's high performance applications.

– 2 pA/√Hz Noninverting Current Noise

– 10 pA/√Hz Inverting Current Noise

– 3 nV/√Hz Voltage Noise

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

puts the amplifier in low power standby mode, and

lowers the quiescent current from 4.8 mA to 270 µA.

•

High Output Current Drive: 260 mA

High Slew Rate: 1300 V/µs (R_L= 100 Ω,

V_O= 8 V_PP

)

•

Wide Bandwidth: 90 MHz (G = 2, R_L= 100 Ω)

Wide Supply Range: ±5 V to ±15 V

performance characteristics.

bandwidth of 100 MHz allows for good distortion

characteristics below 10 MHz. Coupled with high

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

amplifiers allow for high output voltage swings at high

frequencies.

Power-Down Feature: (THS3110 Only)

APPLICATIONS

•

Video Distribution

Power FET Driver

Pin Driver

The THS3110 and THS3111 are offered in a 8-pin

SOIC (D), and the 8-pin MSOP (DGN) packages with

PowerPAD™.
