7106

DESCRIPTION 

The UTC 7106 is a high performance, low power,3½ digits A/D 

converter. Included are seven segment decoders, display drivers, a 

reference, and a clock. 

The UTC 7106 is designed to interface with a liquid crystal 

display (LCD) and includes a multiplexed backplane drive. 

The UTC 7106 bring together a combination of high accuracy, 

versatility, and true economy. It features auto zero to less than 

10μV, zero drift of less than 1μV/°C, input bias current of 10pA 

(Max), and rollover error of less than one count. True differential 

inputs and reference are useful in all system, 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.
