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 25鈩?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. Also
available in TSSOP14 for space saving.
