Features and Benefits
- 14-bit resolution
- ±1 LSB DNL
- ±1 LSB INL
- Low noise: 12 nV/√Hz
- Low power: IDD = 10 μA
- 0.5 μs settling time
- 4-quadrant multiplying reference input
- 2 mA full-scale current ± 20%, with VREF= 10 V
- Built-in RFB facilitates voltage conversion
- 3-wire interface
- Ultracompact 8-lead MSOP and 8-lead SOIC packages
The AD5543/AD5553 are precision 16-/14-bit, low power, current output, small form factor digital-to-analog converters (DACs). They are designed to operate from a single 5 V supply with a ±10 V multiplying reference.
The applied external reference, VREF, determines the full-scale output current. An internal feedback resistor (RFB) facilitates the R-2R and temperature tracking for voltage conversion when combined with an external operational amplifier.
A serial data interface offers high speed, 3-wire microcontroller-compatible inputs using serial data in (SDI), clock (CLK), and chip select (CS).
The AD5543/AD5553 are packaged in ultracompact (3 mm × 4.7 mm) 8-lead MSOP and 8-lead SOIC packages.
- Automatic test equipment
- Digitally controlled calibration
- Industrial control programmable logic controllers

The AD5543 is packaged in ultracompact (3 mm × 4.7 mm) 8-lead MSOP and 8-lead SOIC packages. The EVAL-AD5543 board is used in conjunction with the EVAL-SDP-CB1Z system development platform (SDP) board available from Analog Devices, Inc., which is purchased separately from the evaluation board. The USB-to-SPI communication to the AD5543 is completed using this Blackfin®-based development board. The software offers a waveform generator.
The EVAL-AD5543 can also be used for the AD5553 by changing the number of bits written (14 bits) in the input.
Features & Benefits
- Full-featured evaluation board for the AD5543
- Graphic user interface software for board control and data analysis
- Connector to EVAL-SDP-CB1Z system development platform board
- Various power supply options

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.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
