Overview
The ADS8320SHKJ, produced by Texas Instruments, is a 16-bit, high-speed, sampling analog-to-digital (A/D) converter designed to operate within a 2.7-V to 5.25-V supply range. This device is notable for its ultra-low power consumption and high-speed operation, making it ideal for various applications including portable and battery-operated systems, remote data acquisition modules, and simultaneous multi-channel systems. The ADS8320SHKJ features a synchronous serial (SPI/SSI compatible) interface and is available in an 8-pin ceramic surface-mount package, specified for the –55°C to 210°C temperature range.
