The AD3542R is a low drift, dual channel, ultra-fast, 16-bit accuracy, voltage output digital-to-analog converter (DAC) that can be configured in multiple voltage span ranges. The AD3542R operates with a fixed 2.5 V reference.
The device incorporates three drift compensating feedback resistors for the internal 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 −2.5 V to +7.5 V.
The DAC can operate in fast mode for maximum speed or precision mode for maximum accuracy.
The serial peripheral interface (SPI) can be configured in single SPI (classic SPI) mode, dual SPI mode and synchronous dual 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 AD3542R is specified over the extended industrial temperature range (–40°C to +105°C).

Product Lifecycle Recommended for New Designs
This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
Evaluation Kits (1)
The EVAL-AD3542RFMCZ is an evaluation board for the AD3542R ultrafast 16-bit precision DAC. The board allows testing all the output ranges of the DAC, waveform generation, power supply and reference options. The EVAL-AD3542RFMCZ 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.
The user guide covers the details of the configuration and operation of the EVAL-AD3542RFMCZ board and the associated ACE plug-in. For additional information on the DAC operation refer to the AD3542R data sheet.
