RuiMeng Technology officially releases the MS53115 8-channel Sigma-Delta analog-to-digital converter (ADC). This chip offers 24-bit high resolution, a 125 kSPS sampling rate, and a ±10V wide input range, providing a high-performance, highly integrated data acquisition solution for industrial automation systems. It adopts a single-supply architecture (AVDD: 4.5-5.5V; DVDD: 2-5.5V), delivering exceptional performance while significantly reducing system complexity and development time. It is an ideal choice for PLCs, DCS modules, and high-end instrumentation.
Product Highlights
01 High-Precision Measurement Capability
The MS53115 provides 24-bit high resolution and a 125 kSPS sampling rate, enabling precise capture of subtle signal changes. Its ±10V input range (with an extended range of ±20V) allows direct connection to various industrial sensors, effectively replacing complex discrete front-end solutions. At 20 SPS per channel, the chip offers an 85 dB common-mode rejection ratio for 50Hz/60Hz powerline interference, effectively suppressing industrial noise and enhancing system measurement accuracy and reliability.
02 Highly Integrated Design
The chip integrates 8 differential or 16 single-ended input channels, featuring a built-in high-precision 2.5V reference (accuracy ±0.12%, temperature drift ±22 ppm/℃) and a precision-matched resistor network (input impedance 1.5 MΩ). A single chip can handle multi-channel signal acquisition and conditioning, significantly reducing the number of external components and lowering system complexity and BOM costs.
03 Simplified System Architecture
The single-supply design eliminates the need for complex dual-supply architectures required by traditional solutions, greatly simplifying power supply design. Combined with factory pre-calibration, it effectively shortens product development cycles.
04 Industrial-Grade Reliability
With an extended input range of ±20V and excellent anti-interference capability, the MS53115 operates within a temperature range of -40°C to +125°C, ensuring long-term stable performance in harsh industrial environments. Its 3-wire or 4-wire serial digital interface (compatible with SPI, QSPI, MICROWIRE, and DSP) also facilitates system integration.
