JXA8782MN
24-Bit, 8-Channel, 144KSPS Delta-Sigma ADC — Pin-to-Pin Compatible with ADS1278
Product Overview
The JXA8782MN is a high-precision, 24-bit, eight-channel delta-sigma ADC featuring simultaneous sampling and up to 144kSPS per channel. Designed for high-accuracy measurement applications, this device delivers exceptional SNR and THD performance, making it ideal for precision test equipment, seismic monitoring, and medical devices.
Built on an advanced delta-sigma architecture, the JXA8782MN features eight simultaneously sampling channels with 24-bit-bit resolution and supports both high-resolution and high-speed modes. It integrates programmable digital filters and offers flexible serial interface options to simplify integration into precision data acquisition systems.
Selecting the JXA8782MN delivers 24-bit-precision ADC performance with a ~6-week standard lead time and direct FAE support from Shenxin Microchip. As a pin-to-pin compatible alternative to the ADS1278, it enables seamless migration from existing designs without requiring hardware redesign.

Application Areas
ADS1278 Pin-to-Pin Alternative
The JXA8782MN is a pin-to-pin compatible alternative to the ADS127824-bit, offering eight channels with matching resolution, channel count, sample rate, and key AC performance specs.
This device features the same pinout and comparable performance—including 111dB typical SNR and -115dB THD—making it a drop-in replacement for existing ADS1278-based designs. Its eight-channel simultaneous sampling architecture ensures precise phase alignment across all channels, which is critical for multi-channel precision measurement systems.
With a standard ~6-week lead time compared to extended wait times for imported precision ADCs, and backed by Shenxin Microchip's professional FAE support team, the JXA8782MN delivers a reliable supply source for your high-resolution data acquisition needs.
