Product DetailsThe AD5066 is a low power, 16-bit quad-channel, unbuffered voltage output nanoDAC® offering relative accuracy specifications of ±1 LSB INL with individual reference pins and can operate from a single 2.7 V to 5.5 V supply. The AD5066 also offers a differential accuracy specification of ±1 LSB DNL. Reference buffers are also provided on-chip. The part uses a versatile 3-wire, low power Schmitt trigger serial interface that operates at clock rates up to 50 MHz and is compatible with standard SPI®, QSPI™, MICROWIRE™, and most DSP interface standards. The AD5066 incorporates a power-on reset circuit that ensures the DAC output powers up to zero scale or midscale and remains there until a valid write to the device takes place.
Total unadjusted error for the part is <0.8 mV. Zero code error for the part is 0.05 mV typically.
The AD5066 contains a power-down feature that reduces the current consumption of the device to typically 400 nA at 5 V and provides software selectable output loads while in power-down mode.
The outputs of all DACs can be updated simultaneously using the hardware LDAC function, with the added functionality of user software selectable DAC channels to update simultaneously. There is also an asynchronous CLR that clears all DACs to a software-selectable code—0 V, midscale, or full scale.

Tools & Simulations
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.
