ADS1230High-Precision 20-Bit Δ-Σ ADC — Designed specifically for electronic scales, pressure sensors and industrial process control; available from Mingjiada in Shenzhen

I.ADS1230 Product Introduction

The ADS1230 is a high-precision 20-bit Δ-Sigma analogue-to-digital converter (ADC) launched by Texas Instruments (TI), designed specifically for bridge-type sensors. The chip integrates a low-noise, programmable-gain amplifier (PGA), a built-in oscillator and a high-order digital filter, providing a one-stop solution for amplifying, filtering and converting weak bridge sensor signals, thereby eliminating the need for external signal conditioning circuits and simplifying hardware design. It is ideally suited for acquiring weak differential signals in the millivolt range, such as those from weighing systems, strain gauges and pressure sensors, and is the preferred front-end acquisition chip for industrial force measurement and precision weighing equipment. Shenzhen Mingjiada Electronics Co., Ltd. is a stock supplier of the ADS1230, offering genuine, original products with ample stock and the ability to provide bulk supply services.
