The AD3542R is a low drift, dual channel, ultra-fast, 12-/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.

Each DAC incorporates three drift compensating feedback resistors for the internal transimpedance amplifier (TIA) that scales the output voltage. The device has five preconfigured output voltage ranges: 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 AD3542RBCPZ16 (hereafter referred to as AD3542R-16) can operate in fast mode for maximum speed or precision mode for maximum accuracy. The AD3542RBCPZ12 (hereafter referred to as AD3542R-12) has a single operation mode.

The serial peripheral interface (SPI) can be configured in dual synchronous SPI, dual SPI and single SPI (classic SPI) mode with single date rate (SDR) or double data rate (DDR), with logical levels from 1.2 V to 1.8 V.

The AD3542R is specified over the extended industrial temperature range (–40°C to +105°C).

Product Detail

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.
