DESCRIPTION

The TS652 is a differential digitally controled vari-

able gain amplifier featuring a high slew rate of

90V/

µs, a large bandwidth, a very low distortion

and a very low current and voltage noise.

The gain can be set from -9dB to +30dB through a

4bit digital word, with 3dB steps.

The gain monotonicity is guaranteed by design.

This device is particularly intended for applications

such as preamplification in telecommunication

systems using multiple carriers.

APPLICATION

Assymetric Digital Subscriber Line (ADSL).
