This paper provides method for data acquisition system in which ADC LTC 1408 and microcontroller MSP430F2274 of end device (USB chip) in CC2530ZNP mini kit is used. The LTC1408 is a 14-bit, 600ksps ADC with six simultaneously sampled differential inputs and operated on low power voltage. ...
With V /2 set for 2.56 V, this REF 10 mV corresponds to 1/2 LSB and the circuit resolution is 2 °C. Reducing V /2 to 1.28 yields a resolution of 1 °C. Of course, the REF lower V /2 is, the more sensitive the A/D will be to noise. REF Interfacing the SCN...
