Octal, 16-Bit nanoDAC+ with 2 ppm/°C Reference, SPI Interface

Manufactured by:

Product Details

The AD5672R/AD5676R are low power, octal, 12-/16-bit buffered voltage output digital-to-analog converters (DACs). They include a 2.5 V, 2 ppm/°C internal reference (enabled by default) and a gain select pin giving a full-scale output of 2.5 V (gain = 1) or 5 V (gain = 2). All devices operate from a single 2.7 V to 5.5 V supply and are guaranteed monotonic by design. The AD5672R/AD5676R are available in a 20-lead TSSOP package.

The AD5672R/AD5676R also incorporate a power-on reset circuit and a RSTSEL pin that ensures that the DAC outputs power up to zero scale or midscale and remain there until a valid write takes place. Each part contains a per channel power-down feature that reduces the current consumption of the device to 2.5 µA while in power-down mode.

The AD5672R/AD5676R employ a versatile serial peripheral interface (SPI) that operates at clock rates up to 50 MHz, and all devices contain a VLOGIC pin intended for 1.8 V/3 V/5 V logic.

Product Details

This user guide details the operation of the evaluation boards for the AD5676/AD5676R octal channel, voltage output digital-to-analog converter (DAC).

The EVAL-AD5676SDZ/EVAL-AD5676RSDZ evaluation boards help users to quickly prototype new AD5676/AD5676R circuits and reduce design time. The AD5676/AD5676R operate from a single 2.7 V to 5.5 V supply. The AD5676R has an internal 2.5 V reference giving a maximum output voltage of 2.5 V or 5 V. The AD5676 does not have an internal reference; therefore, an ADR431 is provided on-board as a 2.5 V reference source. A different reference voltage can be applied via the EXT_REF SMB connector, if required.

Full data on the AD5676/AD5676R are available in the respective product data sheets, available from Analog Devices, which should be consulted in conjunction with this user guide when using the evaluation boards.

The evaluation boards interface to the USB port of a PC via the SDP board. Software is supplied with the evaluation board to allow the user to program the AD5676/AD5676R.

The evaluation boards are compatible with the EVAL-SDP-CB1Z Blackfin® SDP controller board (SDP-B), which is available for order on the Analog Devices website at
