The AD5061, a member of the Analog Devices, Inc., nanoDAC™ family, is a low power, single 16-bit buffered voltage-out DAC that operates from a single 2.7 V to 5.5 V supply. The device offers a relative accuracy specification of ±4 LSB and operation is guaranteed monotonic with a ±1 LSB DNL specification. The device uses a versatile 3-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 AD5061 is supplied from an external VREF pin. A reference buffer is also provided on-chip. The device incorporates a power-on reset circuit that ensures the DAC output powers up to mid-scale or zero scale and remains there until a valid write takes place to the device. The device contains a power-down feature that reduces the current consumption of the device to typically 330 nA at 5 V and provides software-selectable output loads while in power-down mode. The device is put into power-down mode over the serial interface. Total unadjusted error for the device is <3 mV. This device exhibits very low glitch on power-up.

Evaluation Kits (1)
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).

Precision DAC Error Budget Tool
The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
