Product details
Overview
MCP48FVB04-E/MQ from Microchip Technology is an 8-bit, quad-channel buffered voltage-output DAC with SPI interface, rail-to-rail output, 7.8 µs settling time, and nonvolatile EEPROM configuration memory. It operates from 2.7V to 5.5V and supports internal band gap (1.22V), VDD, or external VREF sources - used in precision sensor calibration and motor control feedback loops where channel independence and power-on repeatability are critical.
For engineers reviewing the MCP48FVB04-E/MQ datasheet, MCP48FVB04-E/MQ pinout, MCP48FVB04-E/MQ application, or MCP48FVB04-E/MQ equivalent, key selection criteria include its 4-channel simultaneous update capability via LAT0/LAT1, WiperLock™ protection against accidental writes, 680 nA power-down current, and support for SPI Mode 0,0/1,1 up to 20 MHz write speed.
Technical Context
The MCP48FVB04-E/MQ implements a resistor ladder architecture with buffered voltage outputs per channel, selectable gain (1x or 2x) when using external VREF, and dual VREF inputs (VREF0/VREF1) enabling independent reference sourcing for two channel pairs. Its WiperLock™ functionality requires high-voltage activation (9.0–12.5V on LAT0/HVC) to enable EEPROM writes or register updates.
It features dedicated latch pins (LAT0/HVC and LAT1) for synchronous multi-channel updates, programmable power-on reset (POR) output values stored in EEPROM, and auto-recall of both DAC register contents and configuration bits (reference source, gain, power-down state) after reset - ensuring deterministic analog output at startup without host intervention.

Pinout & Package
Package: 20-lead 5 mm × 5 mm VQFN with exposed thermal pad (EP). Compact footprint supports high-density PCB layouts while maintaining thermal performance in thermally constrained applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Supply voltage input | Primary power rail (2.7–5.5V); powers analog and digital sections and serves as optional DAC reference |
| VSS | Ground reference | Analog/digital common ground; must be low-impedance for noise-sensitive DAC operation |
| VREF0 / VREF1 | External reference inputs | Dual independent reference inputs for channel pairs (0/2 and 1/3); support buffered/unbuffered modes |

| SDI / SDO | SPI data in/out | Full-duplex serial interface; SDI accepts 24-bit commands; SDO returns status or register reads |
| LAT0/HVC | Latch 0 / High-voltage control | Simultaneously latches DAC0/DAC2 outputs; doubles as HV input (9–12.5V) to enable WiperLock™ |
| LAT1 | Latch 1 | Latches DAC1/DAC3 outputs; enables synchronized 4-channel updates without software overhead |
| NC | No connect | Unbonded pins (pins 5, 6, 7, 8, 9, 10, 12, 13, 14, 15); must remain unconnected per design |
Key Features
| Feature | Design Value |
|---|---|
| WiperLock™ technology | Prevents unintended DAC register or EEPROM changes via dedicated high-voltage (≥9V) enable signal on LAT0/HVC |
| Nonvolatile EEPROM configuration | Stores POR/BOR output value, reference/gain/power-down settings, and auto-recalls them at every power cycle |
| Dual independent VREF inputs | Allows separate precision references for two channel groups (0/2 and 1/3), eliminating crosstalk in mixed-signal systems |
| Selectable output gain | 1x or 2x gain (when not using VDD as reference); extends effective output range without external op-amps |
| Low-power power-down modes | Three configurable states (high-Z output + 125 kΩ or 1 kΩ pull-down) minimize system standby current |
Applications
| Motor Control Feedback | Sensor Calibration |
|---|---|
Use Scenario: Generating precise bias voltages for current-sense amplifier offsets in BLDC motor drivers. IC Role / Device Role / Timing Role: Quad DAC provides independent, synchronized offset correction for four phase-current measurement channels.

IC Role / Device Role / Timing Role: Delivers stable reference voltages to sensor front-end amplifiers during factory calibration and field recalibration. Use Value: EEPROM-stored settings ensure repeatable sensor output post-power-cycle; 680 nA power-down current extends battery life. |
| Data Acquisition System | Industrial Process Control |
Use Scenario: Providing programmable reference levels for ADC input ranges in modular DAQ modules. IC Role / Device Role / Timing Role: Supplies matched, rail-to-rail reference voltages to four independent ADC channels with simultaneous update via LAT0/LAT1. Use Value: 7.8 µs settling time enables >100 kSPS system throughput; dual VREF inputs prevent inter-channel interference. | Use Scenario: Driving analog inputs of PLC analog output modules for valve/pump actuation signals. IC Role / Device Role / Timing Role: Generates isolated 0–5V/0–10V control signals from microcontroller SPI commands with deterministic startup behavior. Use Value: Auto-recall of EEPROM-configured POR values guarantees safe default output (e.g., 0V) on cold start - critical for fail-safe operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP48FEB04-E/MQ | Same 8-bit quad DAC but with EEPROM memory for DAC register storage (not just configuration); supports auto-recall of last output value | Required when deterministic output value retention across power cycles is mandatory (e.g., safety-critical actuator hold) | Select MCP48FEB04-E/MQ if DAC register persistence is needed; MCP48FVB04-E/MQ stores only configuration, not output data |
| AD5686RACPZ-RL7 | 4-channel 16-bit DAC with internal 2.5V reference, 1.8–5.5V supply, and 8 µs settling; includes power-on reset but no WiperLock™ | Better resolution and integrated reference simplify BOM; lacks hardware write-protection and dual VREF flexibility | Choose AD5686RACPZ-RL7 for higher precision (<0.1% FSR INL) and reduced external components; accept trade-off in configurability and security |
Compared with MCP48FEB04-E/MQ, the MCP48FVB04-E/MQ omits DAC register EEPROM storage - reducing cost and write endurance requirements while retaining full configuration recall. Against AD5686RACPZ-RL7, it trades resolution and integrated reference for WiperLock™ security, dual VREF inputs, and lower power-down current (680 nA vs. 2 µA).

FAQ
What is the maximum SPI clock frequency supported by the MCP48FVB04-E/MQ?
The MCP48FVB04-E/MQ supports SPI write operations up to 20 MHz and read operations up to 10 MHz. This allows rapid register updates in real-time control loops. The device is compatible with SPI Modes 0,0 and 1,1, and its input buffers support interfacing with low-voltage logic families. Timing compliance must be verified against DS20006362A-page 17's tSCK parameter under actual VDD and load conditions.
Does the MCP48FVB04-E/MQ support true simultaneous output updates across all four channels?
Yes, the MCP48FVB04-E/MQ supports true simultaneous updates via its dual latch architecture: LAT0/HVC controls DAC0 and DAC2, while LAT1 controls DAC1 and DAC3. Asserting both latches synchronously achieves coordinated 4-channel output transitions. This eliminates inter-channel skew in time-critical applications like multi-phase motor control or synchronized sensor excitation.
How does WiperLock™ protection work on the MCP48FVB04-E/MQ?
WiperLock™ on the MCP48FVB04-E/MQ requires applying 9.0–12.5V to the LAT0/HVC pin to enter programming mode before executing EEPROM writes or DAC register updates. This hardware-level lock prevents accidental changes due to noise or firmware bugs. Once enabled, standard SPI commands configure the device; the high-voltage signal must be removed to exit programming mode and restore normal operation.
What reference voltage options are available for the MCP48FVB04-E/MQ, and how do they affect output range?
The MCP48FVB04-E/MQ supports three reference sources: internal 1.22V band gap (gain 2x or 4x), VDD (gain 1x), or external VREF on VREF0/VREF1 (gain 1x or 2x, buffered or unbuffered). Output range is always 0V to GAIN × VREF. For example, with VREF0 = 2.048V and gain = 2x, VOUT spans 0–4.096V. Using VDD = 5.5V as reference yields 0–5.5V full-scale output.
What is the power-down current consumption of the MCP48FVB04-E/MQ, and how is it configured?
The MCP48FVB04-E/MQ draws 680 nA typical in power-down mode (PDnB:PDnA = 01), with output disabled and high-impedance. Two additional pull-down options (125 kΩ or 1 kΩ to VSS) are selectable via configuration bits. Power-down is entered via SPI command and maintains EEPROM and register state. Recovery time is negligible - output resumes within 10.5 µs after exiting power-down.
