概述
Description
AD5687RBRUZ is a quad 16-bit voltage-output DAC from Analog Devices with an I2C-compatible serial interface. It provides four buffered outputs (VOUTA–VOUTD) whose full-scale range is set by an external reference. Key features include monotonic 16-bit performance, low glitch energy, and flexibility in update modes (single-channel or simultaneous updates). Each channel supports its own power-down while the device can also power down globally for low power. It operates from a 2.7–5.5 V supply and is suitable for precision instrumentation, calibration, waveform generation, and other analog-control applications. The RBRUZ suffix indicates the specific packaging/tape-and-reel and RoHS-compliant option. For exact pinout, timing, reference configuration, and electrical specifications, refer to the AD5687R datasheet.
