| TS941 TS942 TS944 OUTPUT RAIL TO RAIL MICROPOWER OPERATIONAL AMPLIFIERS s s s s s s s s RAIL TO RAIL OUTPUT VOLTAGE SWING MICROPOWER CONSUMPTION (1.2A) SINGLE SUPPLY OPERATION (2.7V 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 Output 1 5 VCC VDD Non-inverting input 2 DESCRIPTION The TS94x (Single, Dual & Quad) is Operational Amplifier characterized for 2.7V 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.
