DESCRIPTION
The TS652 is a differential digitally controled vari-
able gain amplifier featuring a high slew rate of
90V/碌s, 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.
