GENERAL DESCRIPTION The AD5443, AD5446,and AD5453 are CMOS 12-bit, 14-bit, The applied external reference input voltage (V ) determines REF and 14-bit, respectively, current output, digital-to-analog the full-scale output current. An integrated feedback resistor converters (DACs). The AD5443 operates from a 3 V to 5.5 V (R ) provides temperature tracking and full-scale voltage output FB power supply, while the AD5446 and AD5453 operate from a when combined with an external current-to-voltage precision single 2.5 V to 5.5 V power supply. These devices are well suited amplifier. for portable battery-powered and applications such as waveform The AD5443 and AD5446 are available in small 10-lead MSOP generation and analog processing. packages, while the AD5453 is available in small 8-lead TSOT, Because of the CMOS submicron manufacturing process, these MSOP packages, also comes in 8-lead LFCSP. parts offer excellent 4-quadrant multiplication characteristics of The EV-AD5443/46/53SDZ board is used in conjunction with 10 MHz for the AD5443 and up to 12 MHz for the AD5446 and the EVAL-SDP-CB1Z system demonstration platform (SDP) AD5453 DACs. board available from Analog Devices, Inc., which is purchased These DACs use a double-buffered, 3-wire serial interface that separately from the evaluation board. The USB-to-SPI is compatible with SPI, QSPI, MICROWIRE, and most DSP communication to the DAC is completed using this Blackfin- interface standards. On power-up, the internal shift register and based demonstration board. latches are filled with 0s, and the DAC output is at zero scale. In addition for the AD5443 and AD5446, a serial data out pin (SDO) allows for daisy chaining when multiple packages are used. Data readback allows the user to read the contents of the DAC register via the SDO pin. PLEASE SEE THE LAST PAGE FOR AN IMPORTANT WARNING AND LEGAL TERMS AND CONDITIONS. Rev.
