Compatible with ADS1248, GX1248 in Battery Detection

In battery detection applications, analog-to-digital converters are able to convert signals such as analog voltages and currents of batteries into digital signals for subsequent processing and analysis. Through the accurate measurement of battery voltage by ADC, the remaining battery power can be monitored in real time. Secondly, in the process of battery charging and discharging, the analog-to-digital converter is needed to accurately capture the changes in current, which helps to determine whether the battery charging and discharging status is normal, such as whether there is overcharging and overdischarging.

This paper recommends the precision 24-bit GX1248, which includes many integrated features to reduce system cost and component count for sensor measurement applications.The GX1248 includes many integrated features with a low-noise, programmable gain amplifier, a digital filter with single-cycle stabilization, and an internal oscillator. A built-in low-drift voltage reference and two matched programmable excitation current sources (IDACs) are provided. The input multiplexer supports four differential inputs.

In addition, the GX1248 multiplexer integrates sensor burn-in detection, thermocouple voltage bias, system monitoring, and general-purpose digital I/0. The PGA provides selectable gains up to 128 V/V. These features provide a complete front-end solution for temperature sensor measurement applications including thermocouples, thermistors, and Resistance Temperature Detectors (RTDs), as well as other small-signal measurements including resistance bridge sensors. complete front-end solution.

The GX1248 performance parameters are as follows: 

- Up to 8/4 single-ended/differential channels 

- Programmable data rates up to 2kSPS
