3½ DIGIT, LCD DISPLAY, A/D
CONVERTERS
„ 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.
„ FEATURES
*Guaranteed Zero Reading for 0V Input On All Scales
*True Polarity At Zero for Precise Null Detection
*1pA Typical Input Current
*True Differential Input And Reference, Direct Drive
LCD Display
*Low Noise-Less than 15μVp-p
*On chip Clock and Reference
*Low Power Dissipation-Typically Less than 10mW
*No Additional Active Circuits Required
*Enhanced Display Stability
