LTC2440 provide constant output above 2.5v input

[Bhavik Chaudhari]

Hello Frndz,
I am using LTC2440 24 bit ADC in one application. I am getting output according to the input voltage at IN+ pin. But above 2.5v input , I am getting constant output. Please, help to solve this issue.

Thank you

Hi,

datasheet says:

Input Differential Voltage Range (IN+ – IN–) : –VREF/2 to VREF/2

maybe you use 5V as VRef then the input range is -2.5V ... +2.5V
