Overview
The AD5405YCPZ-REEL7, produced by Analog Devices Inc., is a CMOS, 12-bit, dual-channel, current output digital-to-analog converter (DAC). This device is designed to operate from a 2.5 V to 5.5 V power supply, making it versatile for various applications. It features a 6 mm × 6 mm, 40-lead LFCSP package and includes 4-quadrant resistors necessary for bipolar operation and other configuration modes. The DAC uses data readback, allowing users to read the contents of the DAC register via the DB pins. On power-up, the internal register and latches fill with 0s, and the DAC outputs are at zero scale.
