... 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 ...

... Compared with other voltage comparator devices that require 100 mV overdrive voltages, or multiple stage circuits that include input preamp, etc., the ALD2321A/ ALD2321B/ ALD2321 can perform all input to output functions in one device with minimal delay time and with as low as a 1mV signal. The ALD2321A/ ALD2321B/ ALD2321 is supplied with 4 external e-trim pins, VE11, VE12, VE21 and VE22 ...
