Product Details

The AD5444 / AD5446 are CMOS 12-bit and 14-bit, current output, digital-to-analog converters (DACs). Operating from a single 2.5 V to 5.5 V power supply, these devices are suited for battery-powered and other applications.

As a result of the CMOS submicron manufacturing process, these parts offer excellent 4-quadrant multiplication characteristics of up to 12 MHz.

These DACs use a double-buffered, 3-wire serial interface that is compatible with SPI®, QSPI, MICROWIRE, and most DSP interface standards. On power-up, the internal shift register and latches are filled with 0s, and the DAC output is at zero scale.

The applied external reference input voltage (VREF) determines the full-scale output current. These parts can handle ±10 V inputs on the reference, despite operating from a single-supply power supply of 2.5 V to 5.5 V. An integrated feedback resistor (RFB) provides temperature tracking and full-scale voltage output when combined with an external current-to-voltage precision amplifier. The AD5444 / AD5446 DACs are available in small 10-lead MSOP packages, which are pin-compatible with the AD5425 / AD5426 / AD5432 / AD5443 family of DACs.

The EVAL-AD5443/EVAL-AD5446/EVAL-AD5453 board is available for evaluating DAC performance.

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.
