The AD5320 is a single-channel 12-bit DAC chip with SOT-23 package. It operates at a voltage range of 2.7V to 5.5V and has a low power consumption of 140μA. The chip features Rail-to-Rail output and has functions such as micropower operation, power-down, and low power serial interface. It is suitable for applications such as portable battery-powered instruments, digital gain and offset adjustment, programmable voltage and current sources, and programmable attenuators.
The AD5320 is a single‑channel 12‑bit digital‑to‑analog converter offered by Analog Devices. It operates from a single 2.7 V to 5.5 V supply, consumes very low power (≈0.35 mW at 3 V) and provides rail‑to‑rail output swing. The device features a versatile 3‑wire serial interface compatible with SPI, QSPI, MICROWIRE and DSP standards, supporting clock rates up to 30 MHz.
The datasheet includes detailed specifications, pin configurations, timing characteristics, absolute maximum ratings, and application notes such as battery‑powered instruments, programmable voltage sources, and opto‑isolated interfaces. Ordering information for both 6‑lead SOT‑23 and 8‑lead MSOP packages is also provided.
