- Various power supply options
Product DetailsThe AD5545 dual, 16-bit, current output, digital-to-analog converter (DAC) designed to operate from a single 5 V supply. The applied external reference input voltage (VREF) determines the full-scale output current. Integrated feedback resistors (RFB) provide temperature-tracking, full-scale voltage outputs when combined with an external I-to-V precision amplifier.
A double-buffered serial data interface offers high speed, 3-wire, SPI-compatible, and microcontroller-compatible inputs using serial data in (SDI), chip select (CS), and clock (CLK) signals. A common, level-sensitive, load DAC strobe (LDAC) input allows the simultaneous update of all DAC outputs from previously loaded input registers. Additionally, an internal power-on reset forces the output voltage to 0 at system turn-on. An MSB pin allows system reset assertion (RS) to force all registers to zero code when MSB = 0, or to half-scale code when MSB = 1.
The AD5545 is packaged in the compact 16-lead TSSOP. The EV-AD5545SDZ board is used in conjunction with the EVAL-SDP-CB1Z system demonstration platform (SDP) board available from Analog Devices, Inc., which is purchased separately from the evaluation board. The USB-to-SPI communication to the AD5545 is completed using the EVALSDP-CB1Z Blackfin®-based demonstration board.
