Product Details
The MAX11040 is compatible with SPI™, QSPI™, MICROWIRE™, and DSP-compatible 4-wire serial interfaces. An on-board interface logic allows one serial interface (with a single chip select) to control up to eight cascaded devices or 32 simultaneous sampling analog input channels.
The MAX11040 is ideally suited for power-management systems. Each channel includes an adjustable sampling phase enabling internal compensation for phase shift due to external dividers, transformers, or filters at the inputs. The output data rate is adjustable with a 0.065% resolution (at 16ksps or below) to track the varying frequency of a periodic input. An active-low SYNC input allows periodic alignment of the conversion timing of multiple devices with a remote timing source.
The MAX11040 is available in a 38-pin TSSOP package specified over the -40°C to +105°C industrial temperature range.

Description
The MAXSPCSPARTAN6+ evaluation kit (EV kit) is designed to facilitate the use of Maxim ADCs and DACs with any evaluation board made for Xilinx® Spartan® 6 series FPGAs. The EV kit contains the MAX11612 and MAX11040 ADCs and two cascaded MAX5135 DACs. The MAX11612 is a very-low-power, 4-channel, 2-wire, 12-bit, SAR ADC. This ADC operates with a 5V supply and has an internal reference of 4.096V.
The MAX11040 is an SPI™-compatible, 4-channel, simultaneous-sampling, cascadable, 24-bit, sigma-delta ADC. The MAX5135 is the industry's smallest, 12-bit, voltage-output DAC.
Features
- 12-Bit, 2-/4-Channel, SAR ADC Support (MAX11612)
- 24-Bit, 4-Channel, Programmable Data Rate, Sigma-Delta ADC Support (MAX11040)
- 12-Bit, 4-Channel DAC Support (MAX5135)
- Connects with any Spartan 6 Evaluation Boards Through a Standard FMC VITA-57.1 LPC Connector
