DESCRIPTION

The THS7530 is fabricated using Texas Instruments’

state-of-the-art BiCom III SiGe complementary bipolar

process. The THS7530 is a dc-coupled wide bandwidth

amplifier with voltage-controlled gain. The amplifier has

high impedance differential inputs and low impedance

differential outputs with high bandwidth gain control,

output common mode control, and output voltage

clamping.

Signal channel performance is exceptional with 300-MHz

bandwidth, and third harmonic distortion of –61 dBc at

Gain control is linear in dB with 0 V to 0.9 V varying the gain

from 11.6 dB to 46.5 dB with 38.8-dB/V gain slope.

Output voltage limiting is provided to limit the output

voltage swing, and prevent saturating following stages.

The device is characterized for operation over the

industrial temperature range: –40

°C to 85°C.
