Hello All,

I Intend to use the internal temperature sensor of the LPC1549 and I have carefuly read Chapter 31 of UM10736 (Rev 1.1).

The UM gives info about the internal connectivity of the sensor, but really  nothing about the scale of this sensor (weight of an LSB). I need also some information about its precision and its linearity.

The UM says also this :

Configure the system clock to be 50 MHz and select a CLKDIV value of 0 for a
sampling rate of 50 MHz using the ADC CTRL register.

is it really compulsory to setup precisely a 50 MHz samplig rate ? Or maybe it is a max clock rate ?

Thank you,
