2 / 70 page  AFE4490 SBAS602B – DECEMBER 2012 – REVISED FEBRUARY 2013 www.ti.com This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. FAMILY AND ORDERING INFORMATION OPERATING LED DRIVE LED DRIVE CURRENT POWER SUPPLY TEMPERATURE PRODUCT PACKAGE-LEAD CONFIGURATION (mA, max) (V) RANGE AFE4490 QFN-40 Bridge, push-pull 50, 75, 100, 150, and 200 3 to 5.25 –40°C to +85°C AFE4400 QFN-40 Bridge, push-pull 50 3 to 3.6 0°C to +70°C ABSOLUTE MAXIMUM RATINGS (1) Over operating free-air temperature range, unless otherwise noted. VALUE UNIT AVDD to AVSS –0.3 to +7 V DVDD to DGND –0.3 to +7 V AGND to DGND –0.3 to +0.3 V Analog input to AVSS AVSS – 0.3 to AVDD + 0.3 V Digital input to DVDD DVSS – 0.3 to DVDD + 0.3 V Input current to any pin except supply pins(2) ±7 mA Momentary ±50 mA Input current Continuous ±7 mA Operating temperature range –40 to +85 °C Storage temperature range, Tstg –60 to +150 °C Maximum junction temperature, TJ +125 °C Human body model (HBM) ±1000 V JEDEC standard 22, test method A114-C.01, all pins Electrostatic discharge (ESD) ratings Charged device model (CDM) ±500 V JEDEC standard 22, test method C101, all pins (1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing beyond the supply rails must be current-limited to 10 mA or less.
