GENERAL DESCRIPTION

The ALD2302A/ALD2302 are monolithic precision high performance

dual voltage comparators built with advanced silicon gate CMOS

technology. The primary features are: very high typical input impedance

of 10

very low power dissipation of 175µA per comparator; and single (+5V)

or dual (±5V) power supply operation.

The input voltage range includes ground, which makes these compara-

tors ideal for single supply low level signal detection with high source

impedance. The outputs can source and sink current allowing for

application flexibility. They can be used in either wired-OR connection

without pull-up resistor or push-pull configuration. The ALD2302A/

ALD2302 can also be used in wired-OR connection with other open

drain circuits such as the ALD2301/ALD2303 voltage comparators.

The ALD2302A/ALD2302 voltage comparators are ideal for a great

variety of applications, especially in low level signal detection circuits

which require low standby power and high output current. For quad

packages, use the ALD4302A/ALD4302 quad voltage comparator.

APPLICATIONS

• PCMCIA instruments

• MOSFET driver

• High source impedance voltage comparison circuits

• Multiple limit window comparator

• Power supply voltage monitor

• Photodetector sensor circuit

• Multiple relay drivers

BENEFITS

• On-chip input and output buffers

• Precision voltage comparison capability

• Eliminate need for second power supply

• Eliminate pull-up resistor
