Overview
The AD5611BKSZ-REEL7, produced by Analog Devices Inc., is a member of the nanoDAC® family. It is a single, 10-bit, buffered voltage output Digital-to-Analog Converter (DAC) that operates from a single 2.7 V to 5.5 V supply. This DAC is known for its low power consumption, typically 75 µA at 5 V, and is available in compact 6-lead SC70 and LFCSP packages. The device features an on-chip precision output amplifier, enabling rail-to-rail output swing and a versatile 3-wire serial interface compatible with SPI, QSPI™, MICROWIRE™, and DSP interface standards.
