16-bit 8-channel synchronous-sampling SAR ADC, 200 KSPS, built-in analog input clamp protection, AD7606-class application option; P2P status requires FAE confirmation. Designed for power relay protection and industrial DAQ.
The SXA6681AME is a 16-bit 8-channel synchronous-sampling SAR ADC designed for power relay protection and industrial multi-channel acquisition scenarios, intended for AD7606-class power and industrial acquisition applications; P2P status requires FAE confirmation. The device integrates 8 independent sample-and-hold amplifiers and SAR ADC cores on a single chip, with up to 200 KSPS synchronous sampling rate, supporting true bipolar analog inputs (Β±10V/Β±5V selectable), and built-in analog input clamp protection circuits that effectively protect the device and backend circuitry under power system fault and overvoltage conditions.
The SXA6681AME provides both parallel and high-speed serial interfaces (SPI/QSPI) for convenient connection to MCUs, DSPs, and FPGAs. On-chip integrated 2.5V reference and reference buffer minimize peripheral circuitry. The combination of 16-bit resolution, 8-channel synchronization, and built-in clamp makes it an AD7606-class China-based evaluation option for power protection, fault recording, power measurement & control, and industrial DAQ.
For AD7606-based designs, treat SXA6681AME as an evaluation candidate unless FAE provides a project-specific P2P confirmation. Validate pin assignment, package, electrical limits, timing, interface behavior, EMC, and system performance before production migration. The device has been deployed in volume at multiple power protection and industrial customers. Standard lead time is approximately 6 weeks, with FAE on-site support and reference designs.

The SXA6681AME is an AD7606-class China-based evaluation option with similar system-level use cases in relay protection, power measurement & control, and industrial DAQ. The current FAE Master Matrix does not confirm P2P status; validate pin assignment, package, electrical characteristics, timing, interface behavior, and EMC before production migration. We recommend functional and EMC verification before mass production; our FAE can provide full assistance.
