Hello,
we are using the LPC4337.
We're investigating whether it's possible to measure TWO DIFFERENT analog signals (let's call it signal A and B) with ADC0 channel 1 and ADC1 channel 1?
- we have connected signal A to the dedicated analog Pin "ADC0_1/ADC1_1"
- we have connected signal B to PC_0 (which shall be routed internally to ADC1)
At the moment it seems, that analog signal A and signal B are "some kind of connected" within the LPC4337?
UserManual, Chapter 17 says: "This means that for the parts with shared input channels, input ADC0_n is connected to
channel n on ADC0 and ADC1 and input ADC1_n is connected to channel n on ADC0 and
ADC1, See Table 197 and Table 199".
Is that true? Are channel 1 of ADC0 and ADC1 really connected internally?
If I understand this correctly, it would mean that ADC0 channel 1 and ADC1 channel1 could not be used to measure 2 different analog signal independently?
Or is there a way to configure the LPC4337 so that the two analog signals (Pin "ADC0_1/ADC1_1" and Pin "PC_0) do not electrically influence each other?
