ADS8345EB Description

The ADS8345EB from Texas Instruments is a high-performance, 16-bit SAR (Successive Approximation Register) analog-to-digital converter (ADC) designed for precision measurement applications. It features a single A/D converter with a flexible SPI interface, supporting both single-ended and differential input configurations. The device operates with dual supply voltages (2.7V–3.6V or 5V) for analog and digital domains, ensuring compatibility with a wide range of systems. With a sampling rate of 100k samples per second (SPS) and a 1:1 sample-and-hold (S/H) to ADC ratio, it delivers high-speed, accurate conversions. The ADS8345EB is housed in a 20-pin SSOP package, making it suitable for space-constrained designs.
