Description
ES5129 is a 19,999-count analog-to-digital
converter (ADC) with multiplexed
LCD
display driver. It drives 4-1/2 digits, 4 decimal
points, polarity, continuity and low battery
indicator segments. ES5129 requires a typical
9V power supply for ADC operation. And it
generates a COMMON reference for analog
circuit and a DGND reference for digital
circuit and LCD driver circuit. ES5129 has a
±19,999 counts resolution on both 200.00mV
and 2.0000V ranges. It features high
impedance inputs, excellent differential
linearity, true ratiometric operation and auto
polarity. The only external active component
required is a reference. The underrange and
overrange outputs and the 10:1 range changing
inputs facilitate the design of autoranging
systems. Other features include low battery
detection, continuity check, Display Hold and
controllable decimal points.
