Analog DevicesEVAL-ADN2850SDZ开发套件和工具

evaluation board for evaluating the ADN2850—a dual-channel, 1024-position, nonvolatile memory digital resistor. With versatile programmability, the ADN2850 allows multiple modes of operation, including read/write access in the RDAC and EEMEM registers, increment/decrement of resistance, resistance changes in ±6 dB scales, wiper setting readback, and extra EEMEM for storing user-defined information, such as memory data for other components or a lookup table. The ADN2850 supports a dual-supply ±2.25 V to ±2.75 V operation and a single-supply 2.7 V to 5.5 V operation, making the device suited for battery-powered applications and many other applications. In addition, the ADN2850 uses a versatile SPI-compatible serial interface, allowing speeds of up to 50 MHz. The EVAL-ADN2850SDZ can operate in single-supply and dual-supply mode and incorporates an internal power supply from the USB.
