GENERAL DESCRIPTION

The ALD2321A/ALD2321B/ALD2321 is a monolithic Precision Dual Volt-

age Comparator, each having integrated dual complementary output

drivers. It is constructed using advanced silicon gate CMOS technology.

Key features of the ALD2321A/ALD2321B/ALD2321 include very high

input impedance, very low offset voltage utilizing on-chip e-trim (EPAD

electronic-trimming) technology, flexible multiple output configurations and

fast response time with small overdrive voltage. It is designed for ultra low

level signal detection from high impedance sources. For many applications

the ALD2321A/ALD2321B/ALD2321 can eliminate an input amplification

stage, a precision input bias stage, a signal level shift stage and an output

buffer stage, and do the entire job from low level input signal detection to high

output driver -- all on a single chip.

The input voltage includes ground, making this voltage comparator ideal for

single supply (+5V) or dual supply (± 5V) powered systems. For dual supply

applications, GND pin is connected to the most negative supply instead of

Ground (0.0V). The negative supply voltage can be at any value between

0.0V and -5V. Each voltage comparator is individually trimmed at the factory

for minimum offset voltage at ground voltage potential, making the ALD2321A/

ALD2321B/ALD2321 at its best offset voltage and ready to compare very

low signal level voltages at or near ground potential. Typically a signal less

than 1mV can be resolved and detected reliably without requiring amplifica-

tion. Sensor or detector signals with signal power as low as 0.004pW (4 x

Each voltage comparator has two complementary output pins, one for

Source Output (OUT

complementary output allows maximum circuit design flexibility. The out-

puts can be used as Single-Ended Driver, Multiple WIRED-OR Outputs,

Push-Pull Outputs or Complementary Outputs. The Sink Output can be

used as an open drain output, which has current sink capability of up to

50mA. It can also be connected to an external voltage higher or lower than

V+, which provide level shift of the output swing levels from other than V+

to GND. The Source Output can source up to 2mA and can be used to drive

the base terminal of an external NPN bipolar device or the gate of a N-

channel MOSFET device. Alternatively, the two outputs, Source Output and
