ICL7106CPLZ

ICL7106CPLZ is a high-performance, low-power, 31/2 digit A/D converter. Included are seven segment decoders, display drivers, a reference, and a clock. The ICL7106 is designed to interface with a liquid crystal display (LCD) and includes a multiplexed backplane drive. The ICL7106 brings together a combination of high accuracy, versatility, and true economy. It features autozero to less than 10µV, zero drift of less than 1µV/oC, input bias current of 10pA (max), and rollover error of less than one count. True differential inputs and references are useful in all systems, but give the designer an uncommon advantage when measuring load cells, strain gauges, and other bridge-type transducers. Finally, the true economy of single power supply operation (ICL7106), enables a high-performance panel meter to be built with the addition of only 10 passive components and a display.
