Overview
The ADS8341EB/2K5G4, produced by Texas Instruments, is a 16-bit, 4-channel serial output sampling Analog-to-Digital (A/D) converter. This device features a synchronous serial interface and is designed for low power consumption and high speed, making it ideal for battery-operated systems. The ADS8341 operates from a single supply voltage ranging from 2.7V to 5.25V and includes an onboard multiplexer, allowing for either single-ended or differential input configurations. The converter is fabricated on a 0.6µm CMOS process and includes a sample-and-hold function based on capacitive redistribution.
