provides a high speed USB 2.0 connection from the PC to the component evaluation board. The PC
runs the evaluation software. Each evaluation board, which is an SDP compatible daughter board,
includes the necessary installation file required for performance testing.
Note: it is expected that the analog performance on the two platforms may differ.

Below is presented a picture of SDP-B Controller Board with the EVAL-ADN2850SDZ Evaluation
Board.
The EVAL-ADN2850SDZ evaluation board is a member of a growing number of boards available for
the SDP. Designed to help customers evaluate performance or quickly prototype new ADN2850
circuits and reduce design time, the EVAL-ADN2850SDZ evaluation board can operate in
single-supply and dual-supply mode and incorporates an internal power supply powered from the USB.
The ADN2850 is a dual-channel, nonvolatile memory, digitally controlled resistors with 1024-step
resolution, offering guaranteed maximum low resistor tolerance error of ±8%. The device performs
the same electronic adjustment function as a mechanical rheostat with enhanced resolution, solid
state reliability, and superior low temperature coefficient performance. The versatile programming of
the ADN2850 via an SPI®-compatible serial interface allows 16 modes of operation and adjustment
including scratchpad programming, memory storing and restoring, increment/decrement, ±6 dB/step
log taper adjustment, wiper setting readback, and extra EEMEM for user-defined information such as
memory data for other components, look-up table, or system identification information.
