ALD4301A/ALD4301

QUAD PRECISION CMOS VOLTAGE COMPARATOR WITH OPEN DRAIN DRIVER

GENERAL DESCRIPTION

APPLICATIONS

The ALD4301A/ALD4301 is a monolithic high performance quad

voltage comparator built with advanced silicon gate CMOS technol-

ogy. It features very high typical input impedance of 10¹²Ω; low input

bias current of 10pA; fast response time of 300ns; very low power

dissipation of 55µA per comparator; high output drive and single +5V

or dual ±5V power supply operation.

• High source impedance voltage

comparison circuits

• Dual/Quad limit window comparator

• Power supply voltage monitor

• Photo-detector sensor circuit

• Relay or LED driver

• Oscillators

• Battery operated instruments

• Remote signal detection

The input voltage range includes ground, making this comparator ideal

for low level signal detection with high source impedance. The outputs

are open-drain configuration, allowing maximum application flexibility.

The outputs can be connected to a higher external voltage than V and

used in a wired-OR connection with other open drain circuits such as

ALD2301/ALD2303. They can also be used with push-pull output

types such as ALD2302/ALD4302 voltage comparators simultaneously

with open drain comparators using a common V+. The ALD4301A/

ALD4301 is ideal for a great variety of voltage comparator applica-

tions, especially detection circuits requiring very low input currents

and low standby power, yet retaining high output current capability.
