The input voltage range reflects the maximum allowable voltage where the input bias current is within the specification. 3 At this supply voltage, ensure that the input common-mode voltage is within the input voltage range specification. 4 The AD8220 is characterized from −40°C to +125°C. See the section for expected operation in this temperature range. Typical Performance Characteristics VS + = 5 V, VS− = 0 V, VREF = 2.5 V, TA = +25°C, G = 1, RL = 2 kΩ, unless otherwise noted.
