8-bit DAC with current-source architecture for precision voltage output
The MCP47CVB01-E/MF is an 8-bit digital-to-analog converter from Microchip Technology that delivers a voltage-buffered output using a current-source architecture. It communicates over an I²C interface, making it a straightforward fit for mixed-signal boards where a microcontroller already runs that bus. With a settling time of 16 µs (typical), this DAC updates its output fast enough for most closed-loop control loops — think trimming a power supply setpoint or adjusting a sensor bias voltage on the fly. The ±0.1 LSB INL and ±0.1 LSB DNL mean the output lands within a fraction of a least-significant bit of the ideal value, so you are not chasing calibration offsets across temperature.
Supply rails, temperature grade, and package fit
It comes in a 10-VFDFN exposed-pad package (3x3 mm DFN-10). The exposed pad on the underside needs a thermal via pattern to the ground plane to pull heat out of the die; without that the junction temperature climbs faster than the ambient spec suggests. The surface-mount footprint is standard for this package class — no exotic pad geometry required.
Active lifecycle — sourcing posture
The part ships in Tube packaging, which is typical for low-volume prototyping and small-batch production runs. For higher volumes, check whether Microchip offers a tape-and-reel variant of the same die — the tube quantity is usually 91 pieces per tube for this DFN package.
