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).
