TS635

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 TS635 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 TS635 is fitted out with

Power Down function in order to decrease the

consumption.

The TS635 is housed in a SO8 plastic package

and a SO8 Exposed-Pad plastic package.

APPLICATION

s UPSTREAM line driver for Asymmetric Digital

Subscriber Line (ADSL) (NT).
