Part Details
- 14-Bit DAC; 12-Bit Accuracy Guaranteed
- On-chip, 1.25 V/2.5 V, 5 ppm/°C reference
- Tiny 8-lead SOT-23/MSOP packages
- Power-down to 480 nA @ 5 V, 200 nA @ 3 V
- 3 V/5 V single power supply
- Guaranteed 16-bit monotonic by design
- Power-on reset to zero/midscale
- 3 power-down functions
- Serial interface with Schmitt-triggered inputs
- Rail-to-rail operation
- SYNC interrupt facility
The AD5620 / AD5640 / AD5660, members of the nanoDAC® family of devices, are low power, single, 12-/14-/16-bit, buffered voltage-out DACs and are guaranteed monotonic by design.
The AD5620 / AD5640 / AD5660-1 parts include an internal, 1.25 V, 5 ppm/°C reference, giving a full-scale output voltage range of 2.5 V. The AD5620 / AD5640 / AD5660-2-3 parts include an internal, 2.5 V, 5 ppm/°C reference, giving a full-scale output voltage range of 5 V. The reference associated with each part is available at the VREFOUT pin.
The parts incorporate a power-on reset circuit to ensure that the DAC output powers up to 0 V (AD5620 / AD5640 / AD5660-1-2) or midscale (AD5620-3 and AD5660-3) and remains there until a valid write takes place. The parts contain a power-down feature that reduces the current consumption of the device to 480 nA at 5 V and provides software-selectable output loads while in power-down mode. The power consumption is 2.5 mW at 5 V, reducing to 1 μW in power-down mode.
The AD5620 / AD5640 / AD5660 on-chip precision output amplifier allows rail-to-rail output swing to be achieved. For remote sensing applications, the output amplifier’s inverting input is available to the user. The AD5620 / AD5640 / AD5660 use 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.

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.
