16-bit 8-channel synchronous-sampling SAR ADC, 200 KSPS, built-in analog input clamp protection, Pin-to-Pin compatible with AD7606. Designed for power relay protection and industrial DAQ.
The JXA6681AME is a 16-bit 8-channel synchronous-sampling SAR ADC designed for power relay protection and industrial multi-channel acquisition scenarios, Pin-to-Pin compatible with ADI's AD7606. 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 JXA6681AME 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 ideal China-based alternative to the AD7606 for power protection, fault recording, power measurement & control, and industrial DAQ.
Because the JXA6681AME is highly compatible with the AD7606 in pins, package, functionality, and application circuits, existing AD7606 designs can complete replacement with zero PCB redesign, significantly shortening the replacement cycle. 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 JXA6681AME is a pin-to-pin compatible China-based alternative to the AD7606, highly consistent in resolution, channel count, sampling rate, input range, interface, and package, while retaining the analog input clamp protection most valued by power customers. Existing AD7606-based relay protection, power measurement & control, and industrial DAQ designs can rapidly complete China-based replacement with minimal hardware changes. We recommend functional and EMC verification before mass production; our FAE can provide full assistance.
