8-bit dual DAC with current-source architecture
The MCP47CVB02-E/MF is an 8-bit digital-to-analog converter from Microchip Technology, integrating two D/A converters in a single 10-DFN (3x3 mm) package. It uses a current-source architecture to deliver a voltage-buffered output, settling to within 1 LSB in 16 µs typical — fast enough for closed-loop control loops or audio-level trimming on a mixed-signal board. The dual-channel count means one part handles two independent analog outputs, reducing BOM footprint in multi-rail bias or sensor-calibration circuits. Each channel's output is buffered, so the DAC drives loads directly without an external op-amp for most applications.
±0.1 LSB INL/DNL across industrial temperature range
Integral and differential non-linearity are both rated at ±0.1 LSB maximum — this is a tight spec for an 8-bit DAC, meaning the output code-to-voltage transfer function stays monotonic and accurate across all 256 codes. No missing codes, no dead zones. The INL/DNL spec holds across this band, so calibration constants set at 25°C remain valid in a hot enclosure or cold start. Supply voltage for both analog and digital rails is 1.8V to 5.5V — single-supply operation simplifies power routing. The DAC uses an external or internal reference, selectable via I²C, giving flexibility for ratiometric or absolute output scaling.
