Other Parts Discussed in Thread: MSP430F5528, MSP430FR2153
(1) TMP235 has two accuracy levels,
– A2 Level: ±0.5°C (Typical)
– A4 Level: ±1°C (Typical)
(2) • Positive Slope Sensor Gain, Offset (Typical): – 10 mV/°C, 500 mV at 0°C (TMP235).
And I am selecing an ADC to measure the voltage to get the tempearature. I would like to use the inner ADC of MSP430 as I have seen the TMP23xEVM uses MSP430F5528 as the ADC. http://www.ti.com/tool/tmp235evm
And I want to get 1°C resolution whatever.
(1) Is it enough to select an ADC of 12bit resolution such as the inner ADC of MSP430FR2153 to fulfill the resolution demands of TMP235?
(2) Do I need extra an OP to finish my design?
Thank you!
