DESCRIPTION The TS94x (Single, Dual & Quad) is Operational Amplifier characterized for 2.5V to 10V operation over -40C to +85C temperature range. It is exhibiting an excellent consumption - 1.2A, while featuring 10kHz gain bandwidth product, 1.5mA output capability and output Rail to Rail operation - 2.85V typ @ 3V with RL=10k. The TS94x Op-Amp is ideal for battery-powered systems, where very low supply current and output Rail to Rail are required. Its very low - 1pA typ input bias current and constant supply current over supply voltage enhance TS94x's performance near the end of the life battery charge. APPLICATION

All voltages values, except differential voltage are with respect to network terminal. Differential voltages are non-inverting input terminal with respect to the inverting input terminal. The magnitude of input and output voltages must never exceed VCC +0.3V. Short-circuits can cause excessive heating and destructive dissipation.
