Part Number: TL432B
I do not need a very precise reference power supply, but also to reduce costs. TL432B is a better option.
1. Without calibration and the TL432B REF pin connects to CATHODE, operating temperature from -40oC to +125oC, the maximum output VKA is max. of Vref plus max. of VI(dev), which becomes 2507mV+34mV=2541mV, right?
2. If question 1 is correct, should I add additional deviation came from the effect of temperature coefficient aVref into the maximum output of TL432B calculation?
3. If operating temperature is -40oC to +105oC, the maximum output VKA is 2507mV+ [(105oC-25oC)*34ppm/oC]*2495mV=2507mV+6.786mV= 2513.8mV, is that correct?
