1. CHARACTERISTICS AND SPECIFICATIONS
1.1 Electrical Characteristics
Typical characteristics conditions:
• T
A
= 25 °C, V+ = +5 V, V- = 0 V, VCM = 2.5V
• All voltages are measured with respect to V-
Minimum/Maximum characteristics conditions:
• T
J
= -40°C to +125 °C, V+ = +5 V, V- = 0 V, VCM = 2.5V
Notes: 1. This parameter is guaranteed by design and laboratory characterization. Thermocouple effects prohibit accurate
measurement of these parameters in automatic test systems.
2. 1000-hour life test data @ 125 °C indicates randomly distributed variation approximately equal to measurement
repeatability of 1µV.
3. Measured within the specified common mode range limits.
4. Guaranteed within the output limits of (V+ - 0.3V) to (V- + 0.3V). Tested with proprietary production test method.
5. The device has a controlled start-up behavior due to its complex open-loop gain characteristics. Start-up time
applies when supply voltage is applied or when PDWN is released.
