Product Details

This user guide describes the full featured EVAL-AD5292DBZ board for evaluating the AD5292 digital potentiometer. The AD5292 is a single-channel, 1024-position digital potentiometer with less than ±1% end to end resistor tolerance error and 20-time programmable (20-TP) memory. The AD5292 is capable of operating at high voltages, supporting both dual supply ±10.5 V to ±16.5 V and single supply 21 V to 33 V operation.

The AD5292 uses a serial interface that operates at clock rates of up to 50 MHz and is compatible with the standard serial peripheral interface (SPI).

The EVAL-AD5292DBZ incorporates an internal power supply from the USB and allows an external power supply for the logic voltage levels. The logic voltage levels operate from single 2.7 V to 5.5 V supplies. The EVAL-AD5292DBZ can operate in single supply and dual supply modes, and incorporates an output buffer.

Complete specifications for the AD5292 can be found in the AD5292 data sheet available from Analog Devices, Inc., and must be consulted in conjunction with this user guide when using the evaluation board.
