Description
The TS912 device is a rail-to-rail CMOS dual
operational amplifier designed to operate with
a single or dual supply voltage.
The input voltage range Vicm includes the two
supply rails VCC+ and VCC-.
The output reaches VCC- +30 mV, VCC+ -40 mV,
with RL = 10 kΩ and VCC- +300 mV,
VCC+ -400 mV, with RL = 600 Ω.
This product offers a broad supply voltage
operating range from 2.7 to 16 V and a supply
current of only 200 μA/amp. (VCC = 3 V).
Source and sink output current capability is
typically 40 mA (at VCC = 3 V), fixed by an internal
limitation circuit.
