PRODUCTION DATA
For typical REF31xx-Q1 applications, use these parameters:
The goal for this design is to accurately condition a ±5-V bipolar input voltage into a voltage suitable for conversion by a low-voltage ADC with a 1.25-V reference voltage, VREF, and an input voltage range of VREF / 2. The circuit must function with reduced performance over a wider input range of at least ±6 V to protect from overvoltage conditions.
