12-bit ADC – a mistake in the LPC4370 datasheet documentation (Rev. 2.3)

There is an incorrect equation (4) of op amp’s output voltage in the chapter: 13.9.3 Non-inverting single-ended circuit for input 0 V to 3.3 V (page 147).

At the moment we have the following equation:

Vout = Vcom * R1 / (R1 + R2)

but it should be:

Vout = Vcom * R1 / (R1 + R2) + Vin_pos * R2 / (R1 + R2)

Hi,

I will inform this to our documentation team. Thank you for your feedback.

Have a nice day!
