TS612
DUAL WIDE BAND OPERATIONAL AMPLIFIER
WITH HIGH OUTPUT CURRENT
■LOW NOISE : 3nV/√ Hz, 1.2pA/√ Hz
■HIGH OUTPUT CURRENT : 200mA
■VERY LOW HARMONIC AND INTERMODULATION DISTORTION
■HIGH SLEW RATE : 40V/μs
■SPECIFIED FOR 25Ω LOAD
DESCRIPTION
The TS612 is a dual operational amplifier featuring a high output current (200mA min.), large gain-bandwidth product (130MHz) and capable of driving a 25Ω load with a 160mA output current at
±6V power supply.
This device is particularly intended for applications where multiple carriers must be amplified simultaneously with very low intermodulation products.
The TS612 is housed in SO20 batwing plastic package for a very low thermal resistance. It is also available in TSSOP14 plastic package. This tiny package comes very interesting for surface saving.
The TS612 is fitted out with Power Down function in order to decrease the consumption.
APPLICATION
■UPSTREAM line driver for Asymmetric Digital Subscriber Line (ADSL) (NT).

1.All voltages values, except differential voltage are with respect to network terminal.
2.Differential voltages are non-inverting input terminal with respect to the inverting input terminal.
3.The magnitude of input and output voltages must never exceed VCC +0.3V.
4.An output current limitation protects the circuit from transient currents. Short-circuits can cause excessive heating. Destructive dissipation can result from short circuit on amplifiers.
