MAX11253/MAX11254 Family Evaluation Kit General Description The MAX11253/MAX11254 evaluation kit (EV kit) provides a proven design to evaluate the MAX11253/ MAX11254 family of 16-bit/24-bit, 6-channel, 64ksps, integrated PGA delta-sigma ADCs. The EV kit includes a graphical user interface (GUI) that provides communication from the target device to the PC. The EV kit can operate in multiple modes: 1) 2) 3) Standalone Mode: in “standalone” mode, the EV kit is connected to the PC via a USB cable and performs a subset of the complete EV kit functions with limitations for sample rate, sample size, and no support for coherent sampling. FPGA Mode: in “FPGA” mode, the EV kit is connected to an Avnet ZedBoard™ through a lowpin-count FMC connector. ZedBoard features a Xilinx® Zynq® -7000 SoC, which connects to the PC through an Ethernet port, allowing the GUI to perform different operations with full control over mezzanine card functions. The EV kit with FPGA platform performs the complete suite of evaluation tests for the target IC. User-Supplied SPI Mode: In addition to the USB and FMC interfaces, the EV kit provides a 12-pin Pmod™style header for user-supplied SPI interface to connect the signals for SCLK, DIN, DOUT, and CNVST. The EV kit includes Windows XP®, Windows® 7, and Windows 8.1-compatible software for exercising the features of the IC. The EV kit GUI allows different sample sizes, adjustable sampling rates, internal or external reference options, and graphing software that includes the FFT and histogram of the sampled signals. The ZedBoard accepts a +12V AC-DC wall adapter. The EV kit can be powered by a local +12V supply. The EV kit has on-board transformers and digital isolators to separate the IC from the ZedBoard/on-board processor. The MAX11253/MAX11254 EV kit comes installed with a MAX11253ATJ+ or MAX11254ATJ+ in a 32-pin TQFN-EP package. 19-7584; Rev 2; 4/18 Evaluates: MAX11253/MAX11254 Features ●● High-Speed USB Connector, FMC Connector, and Pmod-Style Connector ●● 8MHz SPI Clock Capability through FMC Connector ●● 8MHz SPI Clock Capability in Standalone Mode ●● Various Sample Sizes and Sample Rates ●● Collects Up to 1 Million Samples (with FPGA Platform) ●● Time Domain, Frequency Domain, and Histogram Plotting ●● Sync In and Sync Out for Coherent Sampling (with FPGA Platform) ●● On-Board Input Buffers: MAX9632 and MAX44205 (Fully Differential) ●● On-Board Voltage References (MAX6126 and MAX6070) ●● Proven PCB Layout ●● Fully Assembled and Tested ●● Windows XP-, Windows 7-, and Windows 8.1-Compatible Software Ordering Information appears at end of data sheet.

EVALUATION KIT AVAILABLE MAX11254 24-Bit, 6-Channel, 64ksps, 6.2nV/√Hz PGA, Delta-Sigma ADC with SPI Interface General Description Benefits and Features The MAX11254 is a 6-channel, 24-bit delta-sigma ADC that achieves exceptional performance while consuming very low power. Sample rates up to 64ksps allow precision DC measurements. The MAX11254 communicates via a SPI serial interface and is available in a small (5mm x 5mm) TQFN package. ●● High Resolution for Industrial Applications that Require a Wide Dynamic Range • 133dB SNR at 50sps • 124dB SNR at 1000sps ●● Longer Battery Life for Portable Applications • 2.2mA Operating Mode Current • 1μA Sleep Current The MAX11254 offers a 6.2nV/√Hz noise programmable gain amplifier (PGA) with gain settings from 1x to 128x. The integrated PGA provides isolation of the signal inputs from the switched capacitor sampling network. The PGA also enables the MAX11254 to interface directly with high-impedance sources without compromising available dynamic range. ●● Single or Split Analog Supplies Provide Input Voltage Range Flexibility • 2.7V to 3.6V (Single Supply) or ±1.8V (Split Supply) ●● Enables System Integration • Low Noise, 6.2nV/√Hz PGA with Gains of 1, 2, 4, 8, 16, 32, 64, 128 • 6-Channel, Fully Differential Input The MAX11254 operates from a single 2.7V to 3.6V analog supply, or split ±1.8V analog supplies, allowing the analog input to be sampled below ground. The digital supply range is 1.7V to 2.0V or 2.0V to 3.6V, allowing communication with 1.8V, 2.5V, 3V, or 3.3V logic. ●● Enables On-Demand Device and System Gain and Offset Calibration • User-Programmable Offset and Gain Registers Applications ●● ●● ●● ●● ●● Robust Performance in a Small Package • -40°C to +125°C Operating Temperature Range • TQFN Package, 5mm x 5mm Analog I/O for Programmable Logic Controllers Weigh Scales Pressure Sensors Battery-Powered Instrumentation Typical Application Circuit 2.7V TO 3.6V REF 10nF AIN0P 2.0V TO 3.6V 1µF REFN REFP AVDD 1nF C0G 1µF DVDD RSTB CSB AIN0N SCLK MAX11254 DIN DOUT AIN5P RDYB 1nF C0G AIN5N GPO0 GPO1 GPOGND CAPP CAPN 1nF C0G CAPREG AVSS 220nF 0603 X7R RESISTIVE BRIDGE MEASUREMENT CIRCUIT, SPI CONFIGURATION 19-7542; Rev 1; 4/15 DGND µC PDF
