ADS1254-EP 增强型产品 24 位 20kHz 低功耗模数转换器

The ADS1254 is a precision, wide dynamic range, delta-sigma, analog-to-digital converter (ADC) with 24-bit resolution. The delta-sigma architecture is used for wide dynamic range and to ensure 24 bits of no missing codes performance. An effective resolution of 19 bits is achieved for conversion rates up to 20 kHz.

The ADS1254 is designed for high-resolution measurement applications in cardiac diagnostics, smart transmitters, industrial process control, weight scales, chromatography, and portable instrumentation. The converter includes a flexible, two-wire synchronous serial interface for low-cost isolation.

The ADS1254 is a multi-channel converter and is offered in an SSOP-20 package.
