TS652

DIFFERENTIAL VARIABLE GAIN AMPLIFIER

s LOW NOISE : 4.6nV/√Hz

s LOW DISTORTION

s HIGH SLEW RATE : 90V/µs

s WIDE BANDWIDTH : 52MHz @ -3dB &

18dB gain

s GAIN PROGRAMMABLE from -9dB to

+30dB with 3dB STEPS

s POWER DOWN FUNCTION

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

s Preamplifier and automatic gain control for

Assymetric Digital Subscriber Line (ADSL).
