MCP4661-103E/ST Frequently Asked Questions (FAQ)
-
The recommended power-up sequence is to apply VDD before applying a clock signal to the SCL pin. This ensures that the device is properly initialized.
-
To retain the wiper position during power-down, the CS pin should be held high and the SCL pin should be held low. This ensures that the device is in a static state and the wiper position is maintained.
-
The maximum frequency of the I2C clock signal is 400 kHz. Exceeding this frequency may result in unreliable operation or device damage.
-
Yes, the MCP4661 can be used as a rheostat by connecting the RH and RL pins together and using the wiper as the output. However, this configuration may affect the device's linearity and accuracy.
-
When the wiper is at the extreme ends of the resistor array, the device may exhibit non-linear behavior. To mitigate this, it is recommended to add external resistors to the RH and RL pins to ensure a minimum resistance value.
