ADC3442EVM: resolution cal

yuhyeon Han

Part Number: ADC3442EVM

I am using adc3442evm .

When calculating the resolution, I want to know if I should use 5V or 1.8V to calculate it.

5V/(2^14) or
1.8V/(2^14)

Hi Yuhyeon,

The differential input voltage for this device is 2Vpp. This means the resolution (often referred to as 1LSB) is 2Vpp/(2^14) = 122uV/code.

Regards, Chase
