TS941-TS942-TS944 Output Rail-to-Rail Micropower Operational Amplifiers n n n n n n n n Rail-to-rail output voltage swing Micropower consumption (1.2µA) Single supply operation (2.5V to 10V) CMOS inputs Ultra low input bias current (1pA) ESD protection (2kV) Latch-up immunity (class A) Available in SOT23-5 micropackage Pin Connections (top view) TS941ILT VDD 2 3 5 V CC 4 Inverting input TS941ID-TS941IDT The TS94x (single, dual & quad) series are operational amplifiers characterized for 2.5V to 10V operation over -40°C to +85°C temperature range. They exhibit 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-amps are ideal for battery-powered systems, where very low supply current and output rail-to-rail are required. Their 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.
