These amplifiers also feature large output voltage swings and a high output current capability to drive standard 150 Ω loads. Running at single or dual supply voltages ranging from 4.5 to 12 V, these amplifiers are tested at 5 V (±2.5 V) and 10 V (±5 V) supplies. The TSH81 also features a standby mode, which provides the operational amplifier with a low power consumption and high output impedance. This function allows power saving or signal switching/multiplexing for high-speed and video applications. For board space and weight saving, the TSH8x series is proposed in SOT23-5, TSSOP8, SO-8 and TSSOP14 plastic micropackages.

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 terminal. 3. The magnitude of input and output must never exceed VCC +0.3 V. 4. Short-circuits can cause excessive heating. 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 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. Table 2.
