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.
