The AD5063, a member of the Analog Device Inc., nanoDAC™ family, is a low power, single 16-bit, unbuffered voltage-output DAC that operates from a single 2.7 V to 5 V supply. The device offers a relative accuracy specification of ±1 LSB, and operation is guaranteed monotonic with a ±1 LSB DNL specification. The AD5063 comes with on-board resistors in a 10-lead MSOP, allowing bipolar signals to be generated with an output amplifier. The device uses a versatile 3-wire serial interface that operates at clock rates up to 30 MHz and that is compatible with standard SPI®, QSPI™, MICROWIRE™, and DSP interface standards. The reference for the AD5063 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 midscale and remains there until a valid write to the device takes place. The device contains a power-down feature that reduces the current consumption of the device to typically 300 nA at 5 V and provides software-selectable output loads while in power-down mode. The device is put into power-down mode via the serial interface. Total unadjusted error for the device is <1 mV.
This device exhibits very low glitch on power-up.
- Available in 10-lead MSOP.
- 16-bit accurate, 1 LSB INL.
- Low glitch on power-up.
- High speed serial interface with clock speeds up to 30 MHz.
- Three power-down modes available to the user.

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.
