8-bit DAC with current-source architecture
The MCP47CVB01-E/UN is an 8-bit digital-to-analog converter from Microchip Technology, delivering a voltage-buffered output through a current-source architecture. It communicates over an I²C interface, making it a straightforward add-on for any microcontroller with a spare I²C bus — no extra pins needed beyond SDA and SCL. With a typical settling time of 16 µs, this DAC can update its output fast enough for audio-level control loops or closed-loop bias adjustments in sensor front-ends. The ±0.1 LSB INL and DNL figures mean the output lands within a fraction of a least-significant bit of the ideal value — no missing codes, no surprises when you step through the full 256-count range.
Supply flexibility and temperature range
The -40°C to +125°C operating range covers automotive under-hood and industrial oven environments — the DAC keeps its accuracy across the full temperature swing. Housed in a 10-MSOP package (3.00 mm width), this is a hand-solderable SMD part — no hot-air station required for prototyping. The surface-mount footprint is compact enough for tight layouts but still forgiving for a hobbyist with a fine-tip iron.
