1 / 18 page March 2009 Rev 5 1/18 18 TS941, TS942, TS944 Output rail-to-rail micropower operational amplifiers Features ■ Rail-to-rail output voltage swing ■ Micropower consumption (1.2 µA) ■ Single supply operation (2.5 V to 10 V) ■ CMOS inputs ■ Ultra low input bias current (1 pA) ■ ESD protection (2 kV) ■ Latch-up immunity (class A) ■ Available in SOT23-5 micropackage Applications ■ Battery-powered systems (alarm) ■ Portable communication systems (pagers) ■ Smoke/gas/fire detectors ■ Instrumentation and sensoring ■ PH meter Description The TS94x (single, dual and quad) series are operational amplifiers characterized for 2.5 V to 10 V operation over -40° C to +85° C temperature range. They exhibit excellent consumption -1.2 µA, while featuring 10 kHz gain bandwidth product, 1.5 mA output capability and output rail-to-rail operation - 2.85 V typical at 3 V with RL=10 kΩ. 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 - 1 pA typical input bias current and constant supply current over supply voltage enhance the TS94x’s performance near the end of the battery charge or battery life. 1 2 3 4 5 Inverting input Non-inverting input Output VDD VCC 1 2 3 4 5 6 7 8 - + Inverting Input 1 N.C.
