I’m working on PSoC 5 kit. I want to sample my signal at a frequency of 360Hz with a resolution of 12bits. If I’m using delta-sigma ADC with a resolution of 12bits I can acquire a minimum of 4000 samples per second. Is there any alternative to reduce the number of samples?

You can increase the resolution to 20 bits( and just take the first 12 bits) ,then you can get the frequency of 360 Hz from Delta -sigma ADC

Another way is to use a timer with the desired frequency. Connect the timer to soc
or
Connect timer to an isr and read-out the ADC within the handler.
