Analog to Digital Converters

ADS8345N Description

The ADS8345N 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-channel ADC 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), making it versatile for mixed-voltage systems. With a sampling rate of 100kSPS and a 1:1 sample-and-hold (S/H) to ADC ratio, it delivers fast and accurate conversions. The ADS8345N is housed in a compact 20-pin SSOP package, suitable for space-constrained designs, and is RoHS3 compliant with MSL 2 (1 Year) moisture sensitivity.
