Other Parts Discussed in Thread: INA326, OPA388, OPA228, OPA320, ADS1258, REF6050, REF6250, REF6150
For a prototype project i need to Measure the environmental data like Temperature, Humidity, IR Radiation, etc. I am planning to use OPA388 and INA326 stages as signal conditioning pre-amplifiers with Low pass filter.
1) In my design the MUX out put will be directly connected to the ADC IN. Planning to use OPA320 / OPA228 as input buffers to the MUX. Which would be the best option Please suggest.
2) I am planning to use ADS1258 with 5Volt Reference. In the Datasheet it is mentioned typical Ref as 4.096V. and ADC reads full scale at 1.06*Vref. In that case i will read fullscale at 4.34V.
My input Swing 0 to 5V, Can i give 5V reference? planning to use REF6050 / REF6150 / REF6250. Which would be the best option Please suggest.
Thanks in Advance.
