Analog Devices Inc. AD5440YRUZ-REEL7

Description
The AD5428/AD5440/AD5447 are dual-channel, current output digital-to-analog converters (DACs) with 8, 10, and 12-bit resolutions, respectively. They operate from a 2.5 V to 5.5 V power supply and feature a 10 MHz multiplying bandwidth. The DACs use data readback, allowing the user to read the contents of the DAC register via the DB pins. On power-up, the internal register and latches are filled with 0s, and the DAC outputs are at zero scale. The applied external reference input voltage (Var) determines the full-scale output current. An integrated feedback resistor (Res) provides temperature tracking and full-scale voltage output when combined with an external 1-to-V precision amplifier.
