ADS1247IPWR – TEXAS INSTRUMENTS

The Texas Instruments ADS1247IPWR is a 24-bit, low-power, delta-sigma ADC with integrated PGA and reference. Packaged in a 28-pin WSON, it operates from a single 2.7V to 5.5V supply, drawing a typical current of 1.1mA. Its input voltage range is ±10V, achievable using the internal programmable gain amplifier (PGA) with gains from 1 to 128. The ADS1247IPWR features a flexible serial interface compatible with SPI and supports various data output formats, including 24-bit signed and unsigned data. Internal circuitry includes a low-noise chopper stabilized amplifier for improved accuracy and a built-in self-test function. This device excels in applications requiring high resolution and low power consumption, such as precision weight scales, medical instrumentation, and industrial process control systems where accurate, low-noise measurements are crucial. The integrated PGA simplifies external component count, reducing board space and cost. Its low power consumption is advantageous in battery-powered systems, and the inherent high resolution minimizes quantization error, leading to improved system accuracy. The device’s robust self-test feature enhances system reliability.
