1. CHARACTERISTICS AND SPECIFICATIONS

Notes: 1. Symbol “•” denotes specification applies over -40 to +85

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 k

Ω 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 when supply voltage is applied or when PDWN is released.
