TS634
TS634
DUAL WIDE BAND OPERATIONAL AMPLIFIER
FOR ADSL LINE INTERFACE
s LOW NOISE : 3.2nV/Hz, 1.5pA/Hz
s HIGH OUTPUT CURRENT : 160mA min.
s VERY LOW HARMONIC AND INTERMODU-
LATION DISTORTION
s HIGH SLEW RATE : 40V/µs
s SPECIFIED FOR 25LOAD
DESCRIPTION
This device is particularly intended for applications
where multiple carriers must be amplified simulta-
neously with very low intermodulation products. It
has been mainly designed to fit with ADSL
chip-set such as ST70134 or ST70135.
The TS634 is a high output current dual operation-
al amplifier, with a large gain-bandwidth product
(130MHz) and capable of driving a 25load at
12V power supply. The TS634 is fitted out with
Power Down function in order to decrease the
consumption.
The TS634 is housed in SO20 batwing plastic
package for a very low thermal resistance.
APPLICATION
s UPSTREAM line driver for Asymmetric Digital
Subscriber Line (ADSL) (NT).
