ADS5474IPFPR

ADS5474IPFPR Description

The ADS5474IPFPR from Texas Instruments is a high-performance 14-bit, 400MSPS pipelined analog-to-digital converter (ADC) designed for demanding signal acquisition applications. Packaged in an 80-pin HTQFP and supplied in Tape & Reel (TR), this ADC integrates a single-channel differential input with a 1:1 sample-and-hold (S/H) to ADC ratio, ensuring precise signal capture. It operates with dual supply voltages (3.1V–3.6V analog, 3V–3.6V digital, and optional 5V analog), making it versatile for mixed-voltage systems. The device features a parallel data interface for high-speed data transfer and includes an internal reference for simplified design integration. With REACH and RoHS3 compliance, it meets stringent environmental standards.
