GENERAL DESCRIPTION
This data sheet describes the evaluation board for evaluating
the AD5292 digital potentiometer. This device is a single-
channel, 1024-position digital potentiometer with less than ±1%
end-to-end resistor tolerance error and 20-times programmable
(20 TP) memory. The AD5292 is capable of operating at high
voltages, supporting both dual supply ±10.5 V to ±15 V and
single supply 21 V to 30 V operation.
The AD5292 part uses a versatile 3-wire serial interface that
operates at clock rates of up to 50 MHz and is compatible
with standard SPI, QSPI™, MICROWIRE™, and DSP interface
standards.
The AD5292 evaluation board incorporates, for the logic
voltage levels, an internal power supply from the USB and
allows an external power supply. The logic voltage levels operate
from single 2.7 V to 5.5 V supplies. The board can operate in
single and dual supply modes and incorporates an output
buffer.
Complete specifications for the AD5292 part can be found in
the AD5292 data sheet available from Analog Devices, Inc., and
should be consulted in conjunction with this data sheet when
using the evaluation board
