Frequently Asked Questions
What resolution and output voltage range does MCP4921T-E/SN provide for precision analog setpoint generation?
The MCP4921T-E/SN is a 12-bit DAC that produces an output voltage up to 4.096 V, giving 4096 discrete voltage steps. At a full-scale reference of 4.096 V, each LSB corresponds to approximately 1 mV, enabling fine-grained setpoint control for process instrumentation and calibration circuits.
How does MCP4921T-E/SN interface with a microcontroller, and what maximum SPI clock rate does it support?
MCP4921T-E/SN uses a 3-wire SPI-compatible serial interface with CS, SCK, and SDI pins. It accepts standard binary-coded 16-bit SPI words and supports clock rates sufficient for real-time waveform updates, making it easy to drive from any microcontroller SPI peripheral without glue logic across an SOIC-8 footprint.
Is MCP4921T-E/SN RoHS compliant, and what package should procurement specify for tape-and-reel ordering?
Yes, MCP4921T-E/SN is fully RoHS and lead-free compliant (JESD-609 code e3). It is supplied in an SOIC-8 package on tape-and-reel reels with a factory lead time of approximately 6 weeks, and the YTEOL rating of 8 years confirms continued availability for multi-year production planning.
When would MCP4921T-E/SN be selected over MCP4911 (10-bit) for a sensor excitation circuit?
MCP4921T-E/SN is preferred over the 10-bit MCP4911 when the excitation accuracy requires better than 0.1% full-scale resolution. With 12 bits at 4.096 V full scale, it delivers approximately 1 mV steps compared to 4 mV on the 10-bit version, which matters in bridge sensor excitation where small output errors shift the zero reading by tens of µV.
