DESCRIPTION

− 2.2 n V/√Hz Voltage Noise

The THS3122/5 are low-noise, high-speed current

High Output Current, 450 m A

feedback amplifiers, with high output current drive. This

High Speed

makes them ideal for any application that requires low

− 128 MHz , −3 d B BW(RL = 50 Ω, RF = 470 Ω)

distortion over a wide frequency with heavy loads. The

− 1550 V/µs Slew Rate (G = 2, RL = 50 Ω)

THS3122/5 can drive four serially terminated video

Low Distortion

The high output drive capability of the THS3122/5

− -80 d Bc (1 MHz, 2 VPP, G = 2)

enables the devices to drive 50-Ω loads with low

Low Power Shutdown Mode (THS3125) distortion over a wide range of output voltages: − 370-µA Shutdown Supply Current −80 −d Bc THD at 2 VPP

−75 −d Bc THD at 8 VPP

Standard SOIC, SOIC Power PAD, and TSSOP Power PAD Package The THS3122/5 can operate from ±5 V to ±15 V supply

voltages while drawing as little as 7.2 m A of supply current per channel. They offer a low power shutdown
