10-bit octal DAC with I²C and wide temperature range
The MCP47FEB18T-E/MQ is an 8-channel, 10-bit digital-to-analog converter from Microchip's MCP series, using an R-2R architecture and communicating over an I²C bus. It offers both buffered and unbuffered voltage output options, with a typical settling time of 7.8 µs — fast enough for closed-loop control loops that update at tens of kilohertz. The INL is ±0.1 LSB and DNL is ±0.0125 LSB, meaning the output stays monotonic and linear within a fraction of a least-significant bit across all codes — important for precision trim or calibration DACs. Operating temperature spans -55°C to 125°C, covering military and extended industrial environments — avionics, downhole tools, or engine-bay modules that see thermal cycling well beyond commercial limits.
ROHS3 compliant, with no exemptions that would complicate EU or California market entry.
