The AD5040, a member of the nanoDAC® family, is a single full accurate 14-bit buffered voltage out DAC in a SOT-23
By combining a 14-bit DAC and high performance output buffer in a SOT-23, the AD5040 delivers a maximum 1 LSB INL linearity error, making it ideal for high performance applications such as open loop control or precision gain and offset. The part utilizes a versatile three-wire serial interface that operates at clock rates up to 30 MHz and is compatible with standard SPI™, QSPI™, MICROWIRE™ and DSP interface standards. The reference for the AD5040 is supplied from an external REF pin with a reference buffer provided on chip to simplify application of the device. The part incorporates a power-on-reset circuit that ensures the DAC output powers up to zero volts and remains there until a valid write takes place to the device. The part also contains a power-down feature that reduces the current consumption of the device to 1 µA at 5 V and provides software selectable output loads while in power-down mode. Power-down mode is activated over the serial interface with very low glitch on power up.

At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
The evaluation board helps users quickly prototype new circuits for the AD5040/AD5060, AD5061, or AD5062 and reduce design time. The AD5040/AD5060, AD5061, and AD5062 operate from a single 2.7 V to 5.5 V supply. An ADR444 is provided on-board as a 4.096 V reference source.
Full data on the AD5040/AD5060, AD5061, and AD5062 is available in the appropriate data sheet, which should be consulted in conjunction with user guide UG-923 when using the evaluation board.
The evaluation board interfaces 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 AD5040/AD5060, AD5061, or the AD5062.
The evaluation boards are compatible with the EVAL-SDP-CB1Z Blackfin® SDP controller board (SDP-B).
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
