They exhibit excellent consumption -1.2 µA, while featuring 10 kHz gain bandwidth product, 1.5 mA output capability and output rail-to-rail operation - 2.85 V typical at 3 V with RL=10 kΩ . The TS94x op-amps are ideal for battery-powered systems, where very low supply current and output rail-to-rail are required. Their very low - 1 pA typical input bias current and constant supply current over supply voltage enhance the TS94x’s performance near the end of the battery charge or battery life.

All voltage values, except differential voltage are with respect to network 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 and destructive dissipation. Rth 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 the ground through only one pin. This is done for all pins. 2/18 TS941, TS942, TS944 Table 2.
