I used ad8253 instrumentation amplifier.I require following points are about ad8253
1.output voltage formula of ad8253 with using ref terminal
2.here "ref terminal " purpose
Thanks for using ADI product.
Here is the formula for computing the output voltage of the AD8253, Vout = G(Vin+ - Vin-) + Vref. It is usually used when it is important to provide an offset to the output of the amplifier to get the required output voltage depending on your application. Usually, the reference pin is used when the amplifier is in single supply configuration. For more information, kindly read the REFERENCE TERMINAL section of the AD8253 datasheet on page 19.
You can also use our instrumentation amplifier diamond plot tool to check if the AD8253 is within the operating range.
Can you share with us your application?
