They exhibit excellent consumption -1.2 A, while featuring 10 kHz gain bandwidth product, 1.5 mA output capability and output rail-to-rail operation 2.85 V typ @ 3 V with RL=10 k . 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 typ input bias current and constant supply current over supply voltage enhance TS94x's performance near the end of the battery charge or battery life. 8 VCC 7 Output 2 6 Inverting Input 2 5 Non-inverting Input 2 Non-inverting Input 1 VDD TS944IN-TS944ID-TS944IDTTS944IPT Output 1 1 Inverting Input 1 2 Non-inverting Input 1 3 VCC 4 Non-inverting Input 2 5 Inverting Input 2 6 Output 2 7 + + + + 14 Output 4 13 Inverting Input 4 12 Non-inverting Input 4 11 VDD 10 Non-inverting Input 3 9 8 Inverting Input 3 Output 3 April 2008 Rev 4 1/19 www.st.com 19 Absolute maximum ratings and operating conditions TS941 TS942 TS944 1 Absolute maximum ratings and operating conditions Table 1.

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 +0.3V. 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 k 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 ). 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. 2/19 TS941 TS942 TS944 Table 2.
