A part rated only to 85°C would require derating or active cooling in that environment; this one does not. Four independent 8-bit DACs on one die, each settling to within 1 LSB in 7.8 µs typical. That settling time defines the per-channel update rate — a 7.8 µs step means you can sequence all four channels at roughly 128 kHz without bus contention, assuming the SPI clock keeps up. The INL of ±0.4 LSB and DNL of ±0.05 LSB guarantee monotonicity across the full code range, which matters for closed-loop actuator trim where a non-monotonic step could cause a control reversal. The output is voltage-unbuffered — the DAC's R-2R ladder drives the output pin directly. This means the output impedance is code-dependent (roughly 10-20 kΩ typical), so the load impedance must be high enough that the voltage error from the divider stays below 1 LSB. A buffer op-amp on the output is standard practice when driving a low-impedance or capacitive load. ## 20-VQFN with exposed pad — board-level checklist The supplier device package identifier is 20-VQFN (5x5), matching the 5x5 mm body size. SPI data interface — the device accepts standard SPI frames; the serial clock and data lines are shared across the four channels with a single chip-select line. Daisy-chaining multiple devices on the same bus is possible if the SPI master supports the protocol extension.","metaTitle":"MCP48FVB04-E/MQ Microchip AEC-Q100 8-Bit Quad DAC, 7.8µs","metaDescription":"Active AEC-Q100-qualified 8-bit quad DAC in 20-VQFN. 7.8µs settling, ±0.4LSB INL, -40 to 125°C.

Grade-1 is the standard for underhood and engine-bay electronics where ambient temperatures exceed 105°C. The qualification covers the full automotive stress test battery: high-temperature operating life, temperature cycling, ESD, latch-up, and package-level reliability."},{"question":"Can the MCP48FVB04-E/MQ replace the MCP4706A1T-E/MAY?","answer":"Not as a drop-in. The MCP4706A1T-E/MAY is a single-channel 8-bit DAC with I²C interface and buffered output, in a different package. The MCP48FVB04-E/MQ is quad-channel with SPI and unbuffered output. A board redesign is required — the interface, channel count, output drive, and package footprint all differ. The MCP48FVB04-E/MQ serves a different application space (multi-channel SPI control vs single-channel I²C)."},{"question":"What compliance documentation comes with the MCP48FVB04-E/MQ?","answer":"RoHS3 compliance is confirmed (no exemptions). The AEC-Q100 qualification report is available from Microchip Technology, covering the full qualification test sequence. PPAP documentation (Production Part Approval Process) is also available for automotive OEM submission. No UL or IEC certification is listed for this device — those standards apply to end-equipment, not semiconductor components."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/MCP48FVB04-E-MQ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/MCP48FVB04-E-MQ when reusing this data.
