Overview
The ADS8355IRTER, produced by Texas Instruments, is a dual, 16-bit, 1-MSPS (mega-samples per second), simultaneous-sampling analog-to-digital converter (ADC). This device is designed to support both single-ended and pseudo-differential analog input signals. It features a flexible serial interface that can operate over a wide range of analog and digital power supplies, making it versatile for various applications. The ADS8355IRTER is fully specified over the extended industrial temperature range of –40°C to +125°C and is packaged in a compact 16-pin WQFN (3-mm × 3-mm) package.
