Product status link The TS951 device is housed in the space-saving 5-pin SOT23 package that makes it well suited for battery powered systems. This micropackage simplifies the PC board TS951, TS952, TS954 design because of its ability to be placed in tight spaces (outside dimensions are: 2.8 mm x 2.9 mm).

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. If V > id 1 V, the maximum input current must not exceed 1 mA. In this case (V > 1 V), an input series resistor id must be added to limit input current. 3. Do not exceed 14 V. 4. Short-circuits can cause excessive heating and destructive dissipation. R are typical values. th 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 ground through only one pin. This is done for all pins.
