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 25Ω LOAD
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 25Ω load 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).
