Overview
The AD5602BKSZ-2500RL7, part of the nanoDAC® family from Analog Devices Inc., is a single 8-bit buffered voltage-out digital-to-analog converter (DAC). This device operates from a single 2.7 V to 5.5 V supply and is known for its low power consumption, typically less than 100 µA at 5 V. The AD5602 is packaged in a tiny 6-lead SC70 package, making it ideal for space-constrained and battery-operated applications. It features an on-chip precision output amplifier that allows for rail-to-rail output swing and includes a power-on reset circuit and power-down feature for enhanced control and power efficiency.
