Features and 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
The AD5543 is a precision, 16-bit, low power, current output, small form factor, digital-to-analog converter (DAC). It is 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 op amp.
A serial data interface offers high speed, 3-wire, microcontrollercompatible inputs using serial data input (SDI), clock (CLK), and chip select (CS).
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.
