3 / 16 page CS3001 CS3002 3 1. CHARACTERISTICS AND SPECIFICATIONS 1.1 Electrical Characteristics V+ = +5 V,V- = 0V,VCM = 2.5 V (Note 1) 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 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.
