Description
The TS914 device is a rail-to-rail CMOS quad 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- +50 mV, VCC+ -50 mV, with RL = 10 kΩ, and VCC- +350 mV, VCC+ 350 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). The source and sink output current capability is typically 40 mA (at VCC = 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 the non-inverting input terminal with respect to the inverting input terminal.
3. The magnitude of input and output voltages must never exceed VCC+ +0.3 V.
4. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous shortcircuit on all amplifiers. These are typical values.
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 g.
