The 8-bit resolution gives 256 output steps; the INL of ±0.25 LSB and DNL of ±0.2 LSB guarantee monotonicity, so every digital code produces a unique analog output with no missing codes. No separate analog supply or voltage regulator is needed, which simplifies the PCB power tree and reduces BOM count. The reference is external — the output voltage span equals the reference voltage times the digital code divided by 256. The SPI data interface uses the same supply voltage as the core, so the digital I/O levels match the microcontroller or FPGA rail without a level shifter. ## 8-MSOP package — board-fit for space-constrained designs The supplier device package is 8-MSOP; the wider 8-TSSOP footprint is also listed as a compatible case code. Surface-mount assembly with standard reflow profiles — no special handling beyond normal MSL precautions. The operating temperature range covers the full industrial and automotive under-hood band. An engine-bay ECU, a solar inverter, or a remote sensor node that sees 105°C ambient still has margin to the 125°C maximum junction temperature. ROHS3 compliant — no restricted-substance exemptions to track.","metaTitle":"Microchip MCP4901-E/MS 8-Bit DAC, SPI, 8-MSOP, Active","metaDescription":"MCP4901-E/MS 8-bit voltage-output DAC from Microchip.
