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
The CYRUSTEK ES5129 is a 4-1/2 digit analog-to-digital converter designed with an integrated multiplexed LCD display driver. It supports two input full-scale ranges: 200mV and 2.0000V, offering high resolution of ±19,999 counts on both scales. The device requires a typical 9V power supply and generates separate reference voltages for analog circuits (COMMON) and digital/LCD driver circuits (DGND). It is available in QFP-44L and DIP-40L packages.
| Resolution/Counting Range | ±19,999 counts |
|---|---|
| Input Full Scale Ranges | 200mV or 2.0000V |
| Resolution on 200mV Scale | 10µV |
| Typical Power Supply Voltage | 9V |
| Operating Temperature Range | 0°C to 70°C |
| Supply Voltage Range | 6.7V to 14V |
The device provides a 10µV resolution when operating on the 200mV scale.
The RANGE pin determines the full-scale range: pulled to DGND or floating for 200.00mV, and pulled to V+ for 2.0000V.
The low battery annunciator activates when the voltage drop between V+ and V- falls below 7.2V.
