OUTPUT RAIL TO RAIL

MICROPOWER OPERATIONAL AMPLIFIERS

■ RAIL TO RAIL OUTPUT VOLTAGE SWING

■ MICROPOWER CONSUMPTION (1.2µA)

■ 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

DESCRIPTION

The TS94x (Single, Dual & Quad) is Operational
Amplifier characterized for 2.7V to 10V operation
over -40°C to +85°C temperature range.

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.

APPLICATION

■ Battery-powered systems (Alarm)

■ Portable communication systems (Pagers)

■ Smoke/gas/fire detectors

■ Instrumentation & sensoring

■ PH Meter

1. All voltages values, except differential voltage are with respect to network terminal.

2. Differential voltages are non-inverting input terminal with respect to the inverting input terminal.

3. The magnitude of input and output voltages must never exceed V

4. Short-circuits can cause excessive heating and destructive dissipation.
