Frequently Asked Questions
What resolution and how many output channels does the MCP4922-E/P provide?
The MCP4922-E/P is a 12-bit dual-channel DAC, providing two independent analog output channels each with 4096 discrete steps. This 12-bit resolution makes it suitable for precision analog signal generation in instrumentation and control applications requiring fine voltage adjustment.
What supply voltage range does MCP4922-E/P support, and can it run from a 3.3 V system?
The MCP4922-E/P operates from a supply voltage of 2.7 V to 5.5 V, making it fully compatible with both 3.3 V and 5 V digital systems. This wide range simplifies integration into mixed-voltage designs without additional level-shifting circuitry.
How does the MCP4922-E/P interface with a microcontroller, and what is the maximum SPI clock speed?
The MCP4922-E/P uses an SPI-compatible serial interface that supports clock speeds up to 20 MHz. It requires only 3 wires (SCK, SDI, CS) plus a LDAC pin for synchronous latch control, minimizing pin usage on the host microcontroller.
What are typical lifecycle and procurement considerations for ordering the MCP4922-E/P in DIP-14 package?
The MCP4922-E/P in DIP-14 package (PDIP-14) is an active product from Microchip with a factory lead time of approximately 6 weeks. It is RoHS-compliant and lead-free (JESD-609 Code e3), making it suitable for designs requiring compliance with environmental regulations. Buyers should plan for the lead time when managing inventory for production runs.
