Shenzhen Meiyuxin Technology Co., Ltd. [distributing TI automotive chips] sells ADS1258IRTCR 24-bit 125kSPS 16-channel delta-sigma ADC with fast channel scanning and automatic sequencer Quality assurance New original! ! !

Product Description:

The ADS1258IRTCR is a 16-channel (multiplexed) low-noise 24-bit delta-sigma () analog-to-digital converter (ADC) that provides single-cycle stable data at channel scan rates from 1.8k to 23.7k per channel per Samples per second (SPS). A flexible input multiplexer accepts a combination of 8 differential or 16 single-ended inputs with a full-scale differential range of 5V or a true bipolar range of ±2.5V when operating with a 5V reference. The fourth-order delta-sigma modulator is followed by a fifth-order sinc digital filter optimized for low noise performance.

The differential outputs of the ADS1258IRTCR multiplexer are accessible to allow signal conditioning prior to the ADC input. Internal system monitor registers provide supply voltage, temperature, reference voltage, gain and offset data.

The ADS1258IRTCR onboard PLL generates the system clock from a 32.768kHz crystal, or it can be overridden by an external clock source. A buffered system clock output (15.7MHz) is provided to drive microcontrollers or other converters.

The ADS1258IRTCR serial digital communication is handled through an SPI™ compatible interface. A simple command word structure controls channel configuration, data rate, digital I/O, supervisory functions, and more.
