Notes: 1. Symbol “•” denotes specification applies over -40 to +85 ° C.
2. This parameter is guaranteed by design and laboratory characterization. Thermocouple effects prohibit
accurate measurement of these parameters in automatic test systems.
3. 1000-hour life test data @ 125 °C indicates randomly distributed variation approximately equal to
measurement repeatability of 1 µV.
4. Measured within the specified common mode range limits.
5. Guaranteed within the output limits of (V+ -0.3 V) to (V- +0.3 V). Tested with proprietary production test
method.
6. PWDN input has an internal pullup resistor to V+ of approximately 800 kΩ and is the major source of
current consumption when PWDN is active (low).
7. The device has a controlled start-up behavior due to its complex open loop gain characteristics. Start-
up time applies to when supply voltage is applied or when PDWN is released.
