Electrical Characteristics
(2.7V ≤ VCC ≤ 5.5V, VCM = GND = 0V, VOUT = VCC/2, RL = 10kΩ connected to VCC/2, SHDN = VCC, TA = -40°C to +125°C, unless otherwise noted.) (Note 5)

Note 1:
Guaranteed by design. Thermocouple and leakage effects preclude measurement of this parameter during production testing. Devices are screened during production testing to eliminate defective units.
Note 2:
IN+ and IN- are gates to CMOS transistors with typical input bias current of 1pA. CMOS leakage is so small that it is impractical to test and guarantee in production. Devices are screened during production testing to eliminate defective units.
Note 3:
Leakage does not include leakage through feedback resistors.
Note 4:
Overload recovery time is the time required for the device to recover from saturation when the output has been driven to either rail.
Note 5:
Specifications are 100% tested at TA = +25°C, unless otherwise noted. Limits over temperature are guaranteed by design. www.maximintegrated.com Maxim Integrated │
