The AD5024 / AD5044 / AD5064 are low power, quad 12-/14-/ 16-bit buffered voltage output nanoDAC® DACs that offer relative accuracy specifications of 1 LSB INL and 1 LSB DNL with individual reference pins and can operate from a single 4.5 V to 5.5 V supply. The AD5024 / AD5044 / AD5064 parts also offer a differential accuracy specification of ±1 LSB. The parts use 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 DSP interface standards. Integrated reference buffers and output amplifiers are also provided on-chip. The AD5024 / AD5044 / AD5064 / AD5064-1 incorporate a power-on reset circuit that ensures the DAC output powers up to zero scale or midscale and remains there until a valid write takes place to the device. The AD5024 / AD5044 / AD5064 / AD5064-1 contain 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. Total unadjusted error for the parts is <2 mV.

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.
