Voltage comparator integrates preamp and outputdriverSilicon-gate electrically programmabletechnology enables industry-standard pinout compatibility,targeting industrial controls and precision instrumentsThe ALD2331/ALD2331A/ALD2331B dual-precisionCMOS voltage comparators are offered as the industry’sfirst integrated precision preamplifier and output driver. Usingthe company’s proprietary EPAD (electrically programmableanalog device) technology, the components are integrated anddie-size reduced to provide a device with an industry-standard8-pin SOIC package. The typical input offset voltages are 0.2 mV(ALD2331A), 0.5 mV (ALD2331B) and 1 mV (ALD2331).Designers no longer need a precision preamp withthese devices because they only require 100 mV for performingoffset comparison.
The comparators target high-performance,high-precision analog applications such as low-level signaldetection circuits that require low stand-by power and high-outputcurrent capability. The devices feature a 1,0 12-Ω typ input impedancewith an input bias current of 10 pA and a response time of 750 nswith a 10-mV input step signal. The comparator also features powerdissipation of 55 µA and single 5-V or dual power supplyoperation. The input voltage of the devices include ground, suitingit for low-level signal detection with high source impedance. (From$1.47 ea/1,000 — available now.)
