Description
ICL7136CPLZ – DIP-40 3 1/2 Digit LCD/LED, Low Power Display, A/D Converters with Overrange Recovery. The Intersil ICL7136 is a high performance, low power 3 1/ 2 digit, A/D converter. Included are seven segment decoders, display drivers, a reference, and a clock. The ICL7136 is designed to interface with a liquid crystal display (LCD) and includes a multiplexed backplane drive. It features auto-zero 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 reference 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, enables a high performance panel meter to be built with the addition of only 10 passive components and a display.
