LOW-NOISE, HIGH-SPEED CURRENT FEEDBACK AMPLIFIERS

FEATURES

APPLICATIONS

Low Noise

Communication Equipment

Video Distribution

Motor Drivers

– 2.9 pA/√Hz Noninverting Current Noise

– 10.8 pA/√Hz Inverting Current Noise

– 2.2 nV/√Hz Voltage Noise

Piezo Drivers

Wide Supply Voltage Range ±5 V to ±15 V

Wide Output Swing

DESCRIPTION

– 25 V Output Voltage, R = 100 Ω, ±15-V

Supply

The THS3112/5 are low-noise, high-speed current

feedback amplifiers, ideal for any application requiring

high output current. The low noninverting current noise

of 2.9 pA/√Hz and the low inverting current noise of 10.8

pA/√Hz increase signal to noise ratios for enhanced

signal resolution. The THS3112/5 can operate from

±5-V to ±15-V supply voltages, while drawing as little as

4.5 mA of supply current per channel. It offers low

High Output Current, 150 mA (Min)

High Speed

– 110 MHz (–3 dB, G=1, ±15 V)

– 1550 V/µs Slew Rate (G = 2, ±15 V)

Low Distortion, G = 2

– -78 dBc (1 MHz, 2 V , 100-Ω load)

Low Power Shutdown (THS3115)

– 300-µA Shutdown Quiescent Current Per

Channel

–78-dBc total harmonic distortion driving 2 V

into a

100-Ω load. The THS3115 features a low power

shutdown mode, consuming only 300-µA shutdown

quiescent current per channel. The THS3112/5 is

packaged in a standard SOIC, SOIC PowerPAD , and

TSSOP PowerPAD packages.
