Maxim MAX11156EVSYS 18-Bit 500k Samples Per Second ADC Evaluation Board

Shenzhen Mingjiada Electronics Co., Ltd., as a globally recognised authorised independent distributor of electronic components, now officially supplies Maxim's MAX11156EVSYS evaluation system. This MAX11156EVSYS evaluation board is specifically designed for the high-performance 18-bit, 500kSPS sampling rate ADC chip MAX11156, providing engineers with a one-stop solution for rapid prototyping and performance verification.

【Core Component: MAX11156 – The Benchmark for 18-Bit ADC Performance】

The core value of the MAX11156EVSYS evaluation board stems from its MAX11156 chip. Since its launch, this chip has defined industry standards through its exceptional integration and performance.

Ultimate Precision and Performance: The MAX11156 delivers true 18-bit lossless resolution, ensuring absolute accuracy in data acquisition. Its typical differential non-linearity (DNL) is as low as ±0.5 LSB, with integral non-linearity (INL) at ±2.5 LSB. Featuring a signal-to-noise ratio (SNR) of 94.6dB and total harmonic distortion (THD) of -105dB, it provides a robust foundation for high-precision measurements.

High Integration and Compact Size: This chip integrates an internal reference voltage source and reference buffer within a diminutive 3mm x 3mm TDFN package. Compared to discrete solutions, this enables end products to save over 70% of PCB space while effectively reducing system complexity and cost.

Simplified Design with ‘Beyond-the-Rails’ Technology: A key innovation is the ‘Beyond-the-Rails’ technology. This enables the chip to directly measure ±5V bipolar analogue input signals from a single +5V supply. Eliminating the need for a negative power rail significantly simplifies front-end signal conditioning circuit design.

Flexible interfacing and low power consumption: The device communicates via an SPI-compatible serial interface, supporting daisy-chain mode for connecting multiple ADCs to facilitate multi-channel system construction. At full-speed sampling of 500kSPS, typical power consumption is just 38.5mW, balancing high performance with energy efficiency.
