ICL7126 Single Chip A/D Converter

® Data Sheet October 25, 2004 ICL7126 FN3084.5 3 1/2 Digit, Low Power, Single Chip A/D Converter The ICL7126 is a high performance, very low power 31/2-digit, A/D converter. All the necessary active devices are contained on a single CMOS IC, including seven segment decoders, display drivers, reference, and clock. The ICL7126 is designed to interface with a liquid crystal display (LCD) and includes a backplane drive. The supply current of 100µA is ideally suited for 9V battery operation. The I.

ICL7126 Features

* auto-zero to less than 10µV, zero drift of less than 1µV/oC, input bias current of 10pA maximum, and rollover error of less than one count. The versatility of true differential input and reference is useful in all systems, but gives the designer an uncommon advantage when measuring load cells, strai
