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 V
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.
