LOW-DISTORTION, HIGH-SPEED, VOLTAGE FEEDBACK AMPLIFIER

•

Unity Gain Stability

The THS4211 and THS4215 are high slew rate, unity

gain stable voltage feedback amplifiers designed to

•

Wide Bandwidth: 1 GHz

run from supply voltages as low as 5 V and as high

•

High Slew Rate: 970 V/µs

as 15 V. The THS4215 offers the same performance

•

Low Distortion

as the THS4211 with the addition of power-down

– –90 dBc THD at 30 MHz

capability. The combination of high slew rate, wide

bandwidth, low distortion, and unity gain stability

– 130 MHz Bandwidth (0.1 dB, G = 2)

make the THS4211 and THS4215 high performance

– 0.007% Differential Gain

devices across multiple ac specifications.

° Differential Phase

Designers using the THS4211 are rewarded with

•

higher dynamic range over a wider frequency band

•

Excellent Video Performance

without the stability concerns of decompensated

amplifiers. The devices are available in SOIC, MSOP
