8 / 40 page LM4930 SNAS212C – JULY 2003 – REVISED MAY 2013 www.ti.com These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. Absolute Maximum Ratings (1) (2) (3) Analog Supply Voltage 6.0V Digital Storage Supply Voltage 6.0V Storage temperature -65°C to +150°C Power Dissipation(4) Internally Limited ESD Susceptibility Human Body Model(5) 2000V Machine Model(6) 200V Junction temperature 150°C Thermal Resistance θJA - YZR0036KRA 105°C/W θJA - NJN0044A (7) 27°C/W (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is functional but do not ensure specific performance limits. Electrical Characteristics state DC and AC electrical specifications under particular test conditions which specifies specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not ensured for parameters where no limit is given, however, the typical value is a good indication of device performance. (2) All voltages are measured with respect to the relevant GND pin unless otherwise specified. (3) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications. (4) The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX ,θJA, and the ambient temperature, TA. The maximum allowable power dissipation is PDMAX = (TJMAX – TA) / θJA or the number given in Absolute Maximum Ratings, whichever is lower. For the LM4930, see power derating currents for more information. (5) Human body model: 100pF discharged through a 1.5k Ω resistor. (6) Machine model: 220pF - 240pF discharged through all pins. (7) The given θA is for an LM4930 packaged in an NJN0044A with the Exposed-DAP soldered to an exposed 2in 2 area of 1oz printed circuit board copper with 16 thermal vias as described in AN-1187. Operating Ratings (1) Temperature Range TMIN ≤ TA ≤ TMAX −30°C ≤ TA ≤ +85°C Supply Voltage DVDD (2) 2.6V - 4.5V AVDD (2) 2.6V - 5.5V (1) The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX ,θJA, and the ambient temperature, TA. The maximum allowable power dissipation is PDMAX = (TJMAX – TA) / θJA or the number given in Absolute Maximum Ratings, whichever is lower. For the LM4930, see power derating currents for more information. (2) Best operation is achieved by maintaining 3.0V ≤ AVDD ≤ 5.0 and 3.0V ≤ DVDD ≤ 3.6V. AVDD must be equal to or greater than DVDD. for proper operation. 8 Submit Documentation Feedback Copyright © 2003–2013, Texas Instruments Incorporated Product Folder Links: LM4930 |
