24-bit 8-channel Δ-Σ precision ADC, up to 144 KSPS, 64-pin TQFP package, <120mW per channel, THD <-108dB / SFDR >115 dBc. Alternative to ADS1278.
The JXA8782MN is a 24-bit 8-channel Δ-Σ (Delta-Sigma) precision analog-to-digital converter designed for high-precision multi-channel measurement scenarios, benchmarked against TI's ADS1278. The device integrates 8 independent high-performance Δ-Σ ADCs in a 64-pin TQFP package, with up to 144 KSPS per channel and excellent THD (<-108 dB) and SFDR (>115 dBc), enabling high-precision synchronous acquisition of weak signals such as acoustics, vibration, and seismic waves.
Per-channel power is under 120 mW, providing excellent overall power control under 8-channel synchronous sampling. On-chip integrated linear-phase digital filters and selectable operating modes (high-resolution/high-speed/low-power) allow flexible tradeoffs between precision, bandwidth, and power. Industrial temperature range, TQFP-64 package, and SPI/frame-sync serial interface facilitate interconnection with MCUs, DSPs, and FPGAs.
The JXA8782MN is the preferred China-based solution for high-precision acoustic measurement, seismic exploration, sonar arrays, medical monitoring, and high-end industrial acquisition. Standard lead time is approximately 6 weeks, with FAE selection and debugging support.
