OUTPUT RAIL TO RAIL
MICROPOWER OPERATIONAL AMPLIFIERS
s RAIL TO RAIL OUTPUT VOLTAGE SWING
s MICROPOWER CONSUMPTION (1.2µA)
s SINGLE SUPPLY OPERATION (2.7V to 10V)
s CMOS INPUTS
s ULTRA LOW INPUT BIAS CURRENT (1pA)
s ESD PROTECTION (2kV)
s LATCH-UP IMMUNITY (Class A)
s 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 op-
eration - 2.85V typ @ 3V with RL=10k.
The TS94x Op-Amp is ideal for battery-powered
systems, where very low supply current and out-
put Rail to Rail are required. Its very low - 1pA typ
input bias current and constant supply current
over supply voltage enhance TS94x’s perfor-
mance near the end of the life battery charge.
APPLICATION
s Battery-powered systems (Alarm)
s Portable communication systems (Pagers)
s Smoke/gas/fire detectors
s Instrumentation & sensoring
s PH Meter
