SA58605
Dual operational amplifier and 2.5 V shunt regulator
2
2002 Mar 25
853–2334 27919
DESCRIPTION
The SA58605 incorporates two op amps and 2.5 V shunt regulator
in an unique circuit configuration. The output of the device is
inverted when the inverting inputs of either or both op amps exceed
the internally set reference voltages at their non-inverting inputs.
Amp “A” is referenced to 2.5 V while Amp “B” is referenced to
154 mV. The SA58605 incorporates a “NOR logic” configuration with
these specific gate levels.
SA58605 supports voltage control and sensor applications such as
AC adapter, switch mode power supply and battery chargers. It is
available in the 5 leaded, SOT23-5 surface mount package.
FEATURES
Low input bias current: 30 nA typ.
Low operating supply current: 1.2 mA typ.
Reference voltages at non-inverting inputs:
– Amp “A” at 2.5 V typ.
– Amp “B” at 154 mV
APPLICATIONS
AC adapter and battery charger
Switched Mode Power Supply (SMPS)
Control voltage/sensor
