Analog to Digital Converters

ADS7949SRTER Description

The ADS7949SRTER from Texas Instruments is a high-performance 8-bit SAR analog-to-digital converter (ADC) designed for precision data acquisition in embedded systems. Packaged in a compact 16-WQFN format and supplied via tape & reel (TR), this ADC integrates a single-channel architecture with a 2 MSPS sampling rate, making it ideal for high-speed signal processing. It operates with dual supply voltages—2.7V to 5.25V (analog) and 1.65V to 5.25V (digital)—ensuring compatibility with mixed-voltage systems. The device supports an external reference voltage and features a 1:1 sample-and-hold (S/H) to ADC ratio, enabling accurate signal capture. Its SPI interface simplifies integration with microcontrollers and DSPs, while its ROHS3 compliance and REACH-unaffected status ensure environmental and regulatory adherence.
