Remember to filter and decouple with a RC circuit if you do not have a separate Vref regulator such as the 78L By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies. ADC just survives with external ref. Page 38 of datasheet shows a VREF pin.

I will connect a voltage divider to the input of the ADC to measure the voltage. Post as a guest Name.

The Varef pin has high impedance when the converter is not operating, however it draws 30pC typically per conversion. If you want tighter tolerance than the 0. Spehro Pefhany k 4 You must provide the reference voltage, which will directly affect the accuracy of your ADC.

78L03 – Three-Terminal Voltage Regulator

Sign up using Email datashet Password. Some sensors are ratio-metric and thus tolerate variations in VREF. Even an inexpensive TL will be okay at maximum conversion rate. I found the equations to calculate the result. AngeloQ 1, 1 5 Tie that to VDD.

Have you examined the code-spread caused by external noise sources that couple into your sensor, or into your wiring between sensor and ADC, or into your ADC IC? Home Questions Tags Users Unanswered. I went through another document which was 18MB and found no Vref.

Bridges, such as strain gauges, are one such sensor.

A reasonable choice would be an external 2. You could use the supply voltage however that is usually a pretty crude and noisy reference source. I see no mention of internal reference in the Table of Contents. Sign up or log in Sign up using Google.
