As alternative you can consider digital thermometers, which is easyer to interface in large numbers and to make temperature sampling simultaneous: http://www.cypress.com/forum/psoc-community-components/component-read-ds18b20-digital-temperature-sensors
Hello, The SAR ADC input resistance is 2.2k and capacitor is 10pF. The equivalent circuit is same as Figure 17 in page no 17(it is applicable for psoc5lp) which is shown in below link: http://www.cypress.com/file/141176/download With SAR_hardware mux, it is not possible to connect the opamp after sar hardware mux. But you can use firmware AMUX bus and connect output of AMUX to opamp to route it to SAR ADC. I attached the project here as reference. Can you please check if this configuration is fine? Thanks Ramesh B
thank you, this is exactly the configuration I was looking for. I can even have 3 control registers with a total of 24 digital outputs and a UART additionally.
For now, I have let the Creator assign the pins. I will now sort the GPIOs to separate the analog and digital lines as far as possible.
