ICL7126

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 100uA is ideally suited for 9V battery operation.

The ICL7126 brings together an unprecedented combination of high accuracy, versatility, and true economy. It features auto-zero to less than 10uV, zero drift of less than 1uV/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, strain gauges and other bridge-type transducers. And finally the true economy of single power operation allows a high performance panel meter or multi-meter to be built with the addition of only 10 passive components and a display.

The ICL7126 can be used as a plug-in replacement for the ICL7106 in a wide variety of applications, changing only the passive components
