Analog to Digital Converters

ADS8681IPW Description

The ADS8681IPW from Texas Instruments is a high-performance, 16-bit, 1-MSPS successive approximation register (SAR) analog-to-digital converter (ADC) designed for precision measurement applications. Housed in a compact 16-TSSOP package, it integrates a single-channel input with a SPI-compatible data interface, ensuring seamless integration into digital systems. The device operates with a 5V analog supply and supports a flexible 1.65V to 5.25V digital supply, making it versatile for mixed-voltage environments. Its 1:1 sample-and-hold (S/H) to ADC ratio ensures accurate signal acquisition, while the inclusion of an internal or external reference enhances design flexibility.
