Frequently Asked Questions
What resolution and maximum output voltage does the MCP4811-E/SN DAC deliver?
The MCP4811-E/SN is a 10-bit DAC with an internal VREF, providing 1024 discrete output steps up to a maximum analog output voltage of 4.176 V. This gives a theoretical LSB step size of approximately 4.1 mV per count, making it suitable for programmable threshold and calibration applications requiring sub-5-mV resolution.
How does the internal voltage reference in MCP4811-E/SN simplify circuit design compared to DACs without VREF?
Because the MCP4811-E/SN integrates its own voltage reference, designers do not need to add an external precision reference IC or resistor divider to set the full-scale output. This reduces BOM count by at least 1 component and eliminates the PCB routing needed for a separate VREF supply, which is especially valuable in compact 8-pin SOIC-8 layouts.
For an SPI-connected microcontroller running at 3.3 V, is MCP4811-E/SN compatible with standard SPI clock speeds?
Yes. The MCP4811-E/SN accepts a standard SPI serial interface with binary input coding and supports clock frequencies up to 20 MHz, making it fully compatible with 3.3 V microcontrollers. The SOIC-8 package keeps data and clock traces short, minimizing signal integrity concerns at these speeds.
What lead time and package options should procurement consider when designing with MCP4811-E/SN?
Microchip quotes a 6-week factory lead time for MCP4811-E/SN in the SOIC-8 (SOIC-8, 0.15-inch body) package. Engineers who need a smaller footprint can evaluate the MCP4811 family in other package variants; for high-volume sourcing, placing orders at least 8 to 10 weeks ahead helps avoid allocation delays in the analog mixed-signal component market.
