AD7568 is an 8-bit eight-channel DAC with 4-quadrant multiplication, single +5V power supply, low power consumption, serial interface, multiple update and reset function.
The AD7568 is an eight‑channel, 12‑bit digital‑to‑analog converter that provides current‑output DACs with separate reference, output and feedback pins. It operates from a single +5 V supply and supports both unipolar (2‑quadrant) and bipolar (4‑quadrant) multiplication modes, making it suitable for process control, test equipment and general instrumentation.
The datasheet details the functional block diagram, pin configurations, absolute maximum ratings, timing specifications, and typical application circuits such as single‑supply current‑mode and voltage‑switching configurations. It also includes performance graphs for settling time, glitch impulse, and channel‑to‑channel isolation.
