Otherwise, use a larger load, such as 10 kΩ. 2 Differential and common-mode input impedance can be calculated from the pin impedance: ZDIFF = 2(ZPIN); ZCM = ZPIN/2. 3 The AD8220 can operate up to a diode drop below the negative supply but the bias current increases sharply. The input voltage range reflects the maximum allowable voltage where the input bias current is within the specification. 4 At this supply voltage, ensure that the input common-mode voltage is within the input voltage range specification. VS + = 5 V, VS− = 0 V, VREF = 2.5 V, TA = 25°C, TOPR = −40°C to +85°C for A and B grades. TOPR = −40°C to +125°C for W grade, G = 1, RL = 2 kΩ1, unless otherwise noted. Table 2.
