Frequently Asked Questions
What is the output voltage resolution of MCP4902 for precision analog control designs?
The MCP4902 provides 8-bit resolution per channel, yielding 256 discrete output voltage steps with a maximum analog output voltage of 5.5 V, suitable for precision calibration, sensor biasing, and analog control loop setpoint generation.
How does the MCP4902 compare to MCP4912 in dual-channel DAC selection for 8-bit vs 10-bit resolution needs?
The MCP4902 provides 8-bit resolution (256 steps) per channel, while the MCP4912 offers 10-bit resolution (1024 steps) for finer voltage granularity. Both share the same 14-pin PDIP package and SPI interface, making pin-compatible migration straightforward for designs needing better resolution.
Can MCP4902 update both output channels simultaneously in a real-time control loop?
Yes. The MCP4902 features a dedicated LDAC pin that simultaneously updates both 8-bit output channels from their internal latches, enabling synchronized dual-channel voltage changes without inter-channel timing skew in real-time control applications.
