Product Details

The AD5641, a member of the nanoDAC® family, is a single, 14-bit, buffered, voltage-out DAC that operates from a single 2.7 V to 5.5 V supply, typically consuming 75 μA at 5 V. The part comes in a tiny LFCSP and SC70 packages. Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The AD5641 uses a versatile 3-wire serial interface that operates at clock rates up to 30 MHz and is compatible with SPI®, QSPI, MICROWIRE, and DSP interface standards. The reference for AD5641 is derived from the power supply inputs and, therefore, gives the widest dynamic output range. The part incorporates a power-on reset circuit, which ensures that the DAC output powers up to 0 V and remains there until a valid write to the device takes place.

The AD5641 contains a power-down feature that reduces current consumption typically to 0.2 μA at 3 V, and provides software-selectable output loads while in power-down mode. The part is put into power-down mode over the serial interface. The low power consumption of the part in normal operation makes it ideally suited to portable battery-operated equipment. The combination of small package and low power makes this nanoDAC device ideal for level-setting requirements such as generating bias or control voltages in space-constrained and power-sensitive applications.


  • Available in a space-saving, 6-lead LFCSP and SC70 packages.
  • Low power, single-supply operation. The AD5641 operates from a single 2.7 V to 5.5 V supply and with a maximum current consumption of 100 μA, making it ideal for battery-powered applications.
  • The on-chip output buffer amplifier allows the output of the DAC to swing rail-to-rail with a typical slew rate of 0.5 V/μs.
  • Reference derived from the power supply.
  • High speed serial interface with clock speeds up to 30 MHz. Designed for very low power consumption. The interface powers up only during a write cycle.
  • Power-down capability. When powered down, the DAC typically consumes 0.2 μA at 3 V.
  • Power-on reset with brownout detection.


  • Voltage level setting
  • Portable battery-powered instruments
  • Digital gain and offset adjustment
  • Programmable voltage and current sources
  • Programmable attenuators

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.
