Maximum Capacitive Load of the Analog Buffer Output of PSoC® 1 – KBA88254

Version: **

 

Question: What is the maximum capacitive load that can be driven by the analog buffer output of PSoC® 1?

 

Answer:

The maximum capacitive load that the analog output buffers can drive without going into oscillation is 200 pF. The GPIO output connected to the analog buffer starts to oscillate if a higher capacitance (approximately 1 μF) is connected at the output. To see this specification, consult the DC Analog Output Buffer Specifications of the PSoC 1 device datasheets.
