HT7126A
31/2 Digit LCD, A/D Converter with Overrange Recovery
The Intersil HT7126A 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 HT7126A is designed to interface with a liquid crystal display (LCD) and includes a multiplexed backplane drive.
The HT7126A brings together a combination of high accuracy, versatility, and true economy. It features auto-zero to less than 10V, zero drift of less than 1V/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.
