Product Details

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.

The MAX11254 offers a 6.2nV/ 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.

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.

View Detailed Evaluation Kit Information

The MAX11253/MAX11254 evaluation kit (EV kit) provides a proven design to evaluate the MAX11253/MAX11254, a 24-bit, 6-channel, 64ksps, integrated PGA delta-sigma ADC. 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:

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 low-pin-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.
