It is exhibiting an excellent consumption - 1.2µA, while featuring 10kHz gain bandwidth product, 1.5mA output capability and output Rail to Rail operation - 2.85V typ @ 3V with RL=10kΩ. 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. 3 5 VCC 4 Inverting input TS941ID-TS941IDT 8 N.C.
