78L03 Datasheet, PDF – Alldatasheet

Sign up using Facebook. Remember to filter and decouple with a RC circuit if you do not have a separate Vref regulator such as the 78L I went through another document which was 18MB and found no Vref. I will connect a voltage divider to the input of the ADC to measure the voltage. Page 38 of datasheet shows adtasheet VREF pin. Your reported voltage will only be as accurate as the VDD.

You could use the supply voltage however that is usually a pretty crude and noisy reference source.

Even an inexpensive TL will be okay at maximum conversion rate. There is a paper discussing this, for a thermistor of Kohm; check on robustcircuitdesign.

You can go as low as 1. AngeloQ 1, 1 5 A reasonable choice would be an external 2. If you want tighter tolerance than the 0.

Spehro Pefhany k 4 Some sensors are ratio-metric and thus tolerate variations in VREF. Have you examined the code-spread caused by external noise sources that couple into your sensor, or into your wiring between datawheet and ADC, or into your ADC IC? This is a datasjeet to the data sheet and a pic of the ADC operation conditions.

Tie that to VDD.

The Varef pin has high impedance when the converter is not operating, however it draws 30pC typically per conversion. You must provide the reference voltage, which will directly affect the accuracy of your ADC.

I found the equations to calculate the result. ADC just survives with external ref. Home Questions Tags Users Unanswered.
