TS634

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 INTERMODULATION 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 simultaneously 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 operational 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.
