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 V
icm
includes the two
supply rails V
CC+
and V
CC
-
.
The output reaches V
CC
-
+30 mV, V
CC+
-40 mV,
with R
L
= 10 kΩ and V
CC
-
+300 mV,
V
CC+
-400 mV, with R
L
= 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.
(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.

1. All voltage values, except differential voltage are with respect to network ground 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
CC+
+0.3 V.
4. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuits on all
amplifiers. These values are typical.
5. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kΩ resistor
between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating.
6. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the
device with no external series resistor (internal resistor < 5
Ω).
This is done for all couples of connected pin combinations
while the other pins are floating.
7. Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly
to ground through only one pin. This is done for all pins.
