Description
The TS912 is a rail-to-rail CMOS dual operational
amplifier designed to operate with a single or dual
supply voltage.
The input voltage range V

includes the two
supply rails V

This product offers a broad supply voltage
operating range from 2.7 to 16 V and a supply
current of only 200 μA/amp (V
CC
= 3 V).
Source and sink output current capability is
typically 40 mA (at V
CC
= 3 V), fixed by an internal
limitation circuit.
