■ RAIL TO RAIL OUTPUT VOLTAGE SWING
■ MICROPOWER CONSUMPTION (20µA)
■ SINGLE SUPPLY OPERATION (2.7V to 10V
■ LOW OFFSET (2mV max for TS93xB)
■ CMOS INPUTS
■ ULTRA LOW INPUT BIAS CURRENT (1pA)
■ ESD PROTECTION (2kV)
■ LATCH-UP IMMUNITY (Class A)
■ AVAILABLE IN SOT23-5 MICROPACKAGE
DESCRIPTION
The TS93x (Single, Dual & Quad) is Operational
Amplifier able to operate with voltage as low as
2.7V and to reach 2.9Vpp of output swing with
RL= 100kΩ when supplied @ 3V. Offering a typi-
cal consumption of only 20µA, it is particularly
well-suited for every kind of battery-supplied applications.
The TS93x is housed in the space-saving 5 pins
SOT23-5 package which simplifies the board design because of the ability to be placed everywhere (outside dimensions are : 2.8mm x 2.9mm).
APPLICATION
■ Battery-powered systems
■ Portable communication systems
■ Alarm, smoke detectors
■ Instrumentation & sensoring
■ PH Meter
■ Digital scales
