•

Low Noise:

•

Video Distribution

–

2.9-pA/

√Hz Noninverting Current Noise

•

Motor Drivers

–

10.8-pA/

√Hz Inverting Current Noise

•

Piezo Drivers

–

2.2-nV/

√Hz Voltage Noise

•

Wide Supply Voltage Range: ±5 V to ± 15 V

DESCRIPTION

•

Wide Output Swing:

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

–

feedback amplifiers, ideal for any application requiring

Supply

high output current. The low noninverting current

•

High Output Current: 150 mA (Min)

noise of 2.9 pA/

√Hz and the low inverting current

noise of 10.8 pA/

√Hz increase signal-to-noise ratios

•

High Speed:

for enhanced signal resolution. The THS3112/5 can

–

110-MHz (–3-dB BW, G = 1, ±15 V)

operate from ±5-V to ±15-V supply voltages, while

–

1550-V/µs Slew Rate (G = 2, ±15 V)

drawing as little as 4.5 mA of supply current per

channel.

It

offers

low

–78-dBc

total

harmonic

•

Low Distortion (G = 2):

–

THS3115 features a low-power shutdown mode,

•

Low-Power Shutdown (THS3115)

consuming only 300-mA shutdown quiescent current

per channel. The THS3112/5 are packaged in

–

300-µA Shutdown Quiescent Current per

standard SOIC, SOIC PowerPAD™, and TSSOP

Channel

PowerPAD packages.
