HI, We are developing a Cryogenic temperature controller using Silicon diode temperature sensor from Lakshore ,which gives output in volts, the sensor data sheet which contains temperature response table which is given here below
The question is : 1. what should be the minimum bit size for data conversion from A to D, ( we have decided to use 24-Bit Delta-Sigma Converter) to get faster response ? 2. On what basis we have to select the bit size ? and we are using MSP430 for interfacing this sensor with LMP90100 (AFE) which has an in built 24bit ds-ADC if we use that ADC our obtained output is 24-bit data, but the controller supports only 16bit of data, how should we address this problem and Pls suggest us in selecting the better ADC for faster response of the sensor. Expecting a positive and speedy reply. Thanking you Karthik.R
