The AD5379 is a 40-channel, 14-bit, parallel and serial input, bipolar voltage-output DAC. It features guaranteed monotonicity to 14 bits, buffered voltage outputs, and an output voltage span of 3.5V×VREF(+).
The AD5379 is a 40‑channel, 14‑bit digital‑to‑analog converter packaged in a 108‑lead CSPBGA. 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, Microwire, and DSP standards.
Key specifications include a supply range of +11.4 V to +16.5 V, short‑circuit current rating of 15 mA, unloaded power dissipation of 850 mW, and a serial clock capability up to 50 MHz. The device also offers features such as simultaneous output updates, programmable gain/offset, and a clear function to reference ground.
