Product Details

The MAX11168 is a 16-bit, 500ksps, SAR ADC offering excellent AC and DC performance with true bipolar input range, internal reference, and small size. The MAX11168 measures a ±5V (10V_P-P) input range while operating from a single 5V supply. A patented charge-pump architecture allows direct sampling of high-impedance sources. The MAX11168 integrates a low drift reference with internal buffer, saving the cost and space of an external reference.

This ADC achieves 92.3dB SNR and -101dB THD. The MAX11168 guarantees 16-bit no-missing codes and ±0.75 LSB INL (typ).

The MAX11168 communicates using an SPI-compatible serial interface at 2.5V, 3V, 3.3V, or 5V logic. The serial interface can be used to daisy-chain multiple ADCs for multichannel applications and provides a busy indicator option for simplified system synchronization and timing.

The MAX11168 is offered in a 10-pin, 3mm x 5mm, µMAX^® package and is specified over the -40°C to +85°C.

MAX11168EVKIT

View Detailed Evaluation Kit Information

The evaluation kit (EV kit) demonstrates the MAX1115X/MAX1116X family of 18-/16-bit SAR 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:

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 limitation 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. The ZedBoard features a Xilinx^® Zynq^® -7000 SoC, that connects to the PC through an Ethernet port, which allows 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 SCLKx, DINx, DOUTx, and CNVSTx.

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 (depending upon target device selected), and graphing software that includes the FFT and histogram of the sampled signals.

The ZedBoard board accepts a +12V AC-DC wall adapter. The EV kit can be powered by a local +20V supply. The EV kit has on-board transformers and digital isolators to separate the IC from the ZedBoard/on-board processor.

The MAX1115X/MAX1116X EV kit comes installed with a MAX1115XEUB+/MAX1116XEUB+ in a 10-pin µMAX^® package, but can also evaluate other pin-compatible parts in the family. For a full list of products supported by this EV kit, see Table 4.
