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).
