ICL7126CPL+

ADCs/DACs - Special Purpose Overview

The ICL7126CPL+ is a low-power, 3 1/2 digit analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It integrates an LCD driver and operates on a single 9 V supply voltage. The device features a dual-slope integration architecture with a parallel interface for data output. Housed in a 40-pin PDIP package, it supports through-hole mounting. The component dissipates up to 1 W of power and functions within a commercial temperature range of 0°C to +70°C.
