Dc elecTrical characTerisTics The
l
denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. V+ = 5V, GND = 0V, No RLOAD, CLOAD = 6pF. VCM = 1.25V, CLHI = V+, PWRADJ = V+, SHDN = 0V unless otherwise noted. VINCM is defined as (IN+ + IN–)/2. VOUTCM is defined as (OUT+ + OUT–)/2. VINDIFF is defined as (IN+ – IN–). VOUTDIFF is defined as (OUT+ – OUT–). See DC test circuit schematic. SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS DC Clamping Characteristics
