Its 4.5 µs typical settling time means the output reaches within 1/2 LSB of the final value in that window — for a control loop running at 100 kHz, that leaves about 5.5 µs for the ADC read and PID calculation before the next update. ## Industrial temperature grade and board integration The 8-MSOP package (3.00 mm width) shares the same footprint as 8-TSSOP — the 0.65 mm pitch demands a clean solder paste stencil and a reflow profile that doesn't shift the part during reflow. The voltage-buffered output can source or sink current through the internal rail-to-rail buffer, but the buffer's drive capability is limited — check the output short-circuit current in the full datasheet if the DAC drives a heavy load directly. No differential output means the signal is single-ended, referenced to the same ground as the analog supply.","metaTitle":"Microchip MCP4901T-E/MS 8-Bit DAC, 4.5µs, SPI, 8-MSOP","metaDescription":"Active Microchip MCP4901T-E/MS 8-bit String DAC, voltage-buffered output, 4.5µs settling, SPI interface, -40 to +125°C.
