Application Areas
ADS1278 PIN-to-PIN replacement
The JXA8782MN is a pin-to-pin compatible alternative to the ADS127824-channel Delta-Sigma ADC, offering full performance parity in resolution, channel count, sampling rate, and key AC specifications.
This device offers the same pinout and comparable performance, including a typical 1dB SNR of 11 and THD of -115dB, making it a direct drop-in replacement for existing ADS1278 designs. Its eight-channel synchronous sampling architecture ensures precise phase matching across all channels, which is critical for multi-channel precision measurement systems.
Standard lead time is approximately 6 weeks, while imported precision ADCs require longer wait times. Backed by Xinweixin's professional FAE support team, JXA8782MN provides a reliable supply source for your high-resolution data acquisition needs.
