Core Advantages

  1. Exceptional Performance Metrics

  • 16-bit resolution, 3MSPS sampling rate: Achieves no-missing-code conversion with an ultra-low latency of 333ns, ensuring real-time system responsiveness.

  • Outstanding dynamic performance: 89.5dB SNR (Signal-to-Noise Ratio) and -109dB THD (Total Harmonic Distortion), maintaining 89.4dB SINAD at 1MSPS sampling rate, perfectly capturing high-frequency weak signals.

  1. Dual-Channel Simultaneous Sampling

    Supports simultaneous acquisition of two fully differential signals, eliminating inter-channel timing skew and providing phase-accurate data for applications such as motor encoders, multi-phase power monitoring, and I/Q demodulation.

  2. High Integration, Simplified Design

  • Built-in reference voltage and buffer: Integrates a 2.5V internal reference and REFby2 common-mode buffer, eliminating external components, reducing noise, and saving PCB space.

  • Data averaging function: Significantly enhances AC performance in high-noise environments through hardware-level signal smoothing technology.

  1. Flexible Interface Options

  • Enhanced SPI: Supports wide read cycles (suitable for low-speed MCU reading) and clock retiming (ideal for long-distance transmission with digital isolators).

  • DDR (Double Data Rate) mode: Optimizes FPGA data acquisition efficiency and improves throughput.

  • Wide voltage compatibility: Digital supply voltage range of 1.65V–5.5V, easily compatible with mainstream logic levels such as 3.3V/1.8V.

Technical Parameters

The MS51224 family also offers options including dual-channel/single-channel, differential, and single-ended/pseudo-differential models.

 

Application Scenarios

Industrial Control: Optical encoders (incremental/absolute), robotic joint sensing

Medical Imaging: Ultrasound/sonar receivers, CT/MRI scanner signal chains

Communications & New Energy: Fiber amplifier (EDFA) gain control, power quality analysis, digital power loop

Test & Measurement: Impedance analyzers, multi-channel synchronous acquisition systems (DAQ)

Looking ahead, RuiMeng Technology will continue to increase R&D investment, uphold a pioneering spirit, and remain committed to providing more high-precision, high-reliability chip solutions for industries such as industrial, communications, automotive, medical, and consumer electronics.
