DS4302 is a 5-bit DAC with three programmable digital outputs.
The DS4302 is a 3‑bit digital‑to‑analog converter (DAC) with an SMBus‑compatible serial interface. It offers two output voltage ranges (0 V‑2.0 V or 0 V‑1.9 V) and can be packaged in 8‑pin SOP or USOP formats. The document lists pin functions, timing diagrams, and operation modes for both write and read transactions.
Key sections cover absolute maximum ratings, recommended operating conditions, DC and AC electrical characteristics, standby supply current, and detailed communication timing. Package information and recommended external components for stable operation are also provided.
