■ LOW NOISE : 3.2nV/√Hz, 1.5pA/√Hz
■ HIGH OUTPUT CURRENT : 160mA min.
■ VERY LOW HARMONIC AND INTERMODU-
LATION DISTO RTION
■ HIGH SLEW RATE : 40V/µs
■ SPECIFIED FOR 25Ω LOAD
DESCRIPTION
This device is particularly intended for applications
where multiple carriers must be amplified simultaneously 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 operational amplifier, with a large gain-band width 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
■ UPSTREAM line driver for Asymmetric Digital
Subs criber Line (ADSL) (NT).
