AD5378 Rev. A is a 32-channel, 14-bit, parallel and serial input, bipolar voltage output DAC from Analog Devices.
The AD5378 is a 32‑channel, 14‑bit digital‑to‑analog converter offered in a 108‑lead CSPBGA package. It provides bipolar voltage outputs with a maximum span of 17.5 V (‑8.75 V to +8.75 V) and supports both parallel and 3‑wire serial interfaces compatible with SPI, QSPI, and Microwire standards.
The document includes full electrical specifications, timing diagrams, pin descriptions, and typical application circuits for use in automatic test equipment, optical attenuators, and industrial control systems. Power‑supply requirements, absolute maximum ratings, and performance characteristics such as resolution, accuracy, and load current are also provided.
