Description
The Intersil HI7106 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 HI7106 is designed to interface with a liquid crystal Display (LCD) and includes a multiplexed backplane drive.
The HI7106 brings together a combination of high accuracy, versatility, and true economy. 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 sys tems, 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.
