MCP4021T-202E/MSVAO Frequently Asked Questions (FAQ)
-
The recommended power-up sequence is to apply VDD first, followed by VSS, and then the logic inputs (CS, SCK, and SI). This ensures proper device operation and prevents latch-up.
-
After power-up, the device is in a undefined state. To ensure proper initialization, send a 'reset' command (0x00) followed by a 'write wiper' command (0x01) to set the wiper to the desired position.
-
The maximum frequency of the SPI clock (SCK) is 10 MHz. Exceeding this frequency may result in incorrect data transfer or device malfunction.
-
Yes, the MCP4021T-202E/MSVAO can be used as a rheostat by connecting the wiper to one of the terminals (RH or RL). However, this configuration may affect the device's linearity and accuracy.
-
The zero-scale error or offset error can be calibrated out by measuring the output voltage at the minimum wiper position and subtracting the error from the desired output voltage. This can be done during the manufacturing process or in the application software.
