Maxim Integrated
Note 1: All devices are 100% production tested at TA = +25°C. Temperature limits are guaranteed by design.
Note 2: The input offset voltage includes the effects of mismatches in the internal VCC/2 resistor dividers.
Note 3: For gain of 0.25V/V, the input common-mode range is -1V to VCC - 2V.
Note 4: The input current of a CMOS device is too low to be accurately measured on an ATE and is typically on the order of 1pA.
Note 5: Parts are functional with fSCLK = 10MHz.
ELECTRICAL CHARACTERISTICS (continued)
(VCC = 5V, VGND = 0V, VINA+ = VINA-, Gain = 10V/V, ROUTA = ROUTB = 1k to VCC/2, TA = TMIN to TMAX, unless otherwise noted.
Typical values are at TA = +25°C.) (Note 1)
