The AD3551R is a low drift, ultra-fast, 16-bit accuracy, current output digital-to-analog converter (DAC) that can be configured in multiple voltage span ranges. The AD3551R operates with a fixed 2.5 V reference.
The device incorporates three drift compensating feedback resistors for the required external transimpedance amplifier (TIA) that scales the output voltage. Offset and gain scaling registers allow for generation of multiple output span ranges, such as 0 V to 2.5 V, 0 V to 5 V, 0 V to 10 V, −5 V to +5 V, and −10 V to +10 V, and custom intermediate ranges with full 16-bit resolution.
The DAC can operate in fast mode for maximum speed or precision mode for maximum accuracy.
The SPI interface can be configured in single SPI (classic SPI) mode, dual SPI mode, and quad SPI mode with single date rate (SDR) or double data rate (DDR), with logical levels from 1.2 V to 1.8 V.
To improve device robustness, cyclic redundancy check (CRC) can be enabled. Multiple error checkers have also been integrated to detect VREF failures or memory map corruption.
The AD3551R is specified over the extended industrial temperature range (–40°C to +105°C).

Evaluation Kits (1)
The EVAL-AD3552RFMCxZ is an evaluation board for the AD3552R ultrafast 16-bit precision DAC. The board is available in two variants: EVAL-AD3552RFMC1Z for higher speed and EVALAD3552RFMC2Z for higher precision, the only difference being the transimpedance amplifier and its corresponding feedback capacitor.
The board allows testing all the output ranges of the DAC, waveform generation, power supply and reference options.
The EVAL-AD3552RFMCxZ interfaces to the USB port of a PC via a system demonstration platform (SDP-H1 board). It can also be connected to a different controller board using the pin header connector at position P5.
