LMP8640 electrical limits also apply to the LMP8640-Q1 unless noted. PARAMETER TEST CONDITIONS MIN(2) TYP(3) MAX(2) UNIT VCM = 2.1 V -900 900 VOS Input Offset Voltage µV VCM = 2.1 V, Over Temperature -1160 1160 TCVOS Input Offset Voltage Drift(4) (5) VCM = 2.1 V 2.6 µV/°C VCM = 2.1 V, VSENSE = 0 V 13 21 IB Input Bias Current (6) µA VCM = 2.1 V, Over Temperature,VSENSE = 0 V 28 eni Input Voltage Noise (5) f > 10 kHz 117 nV/ √Hz (1) Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very limited self-heating of the device such that TJ = TA. No specification of parametric performance is indicated in the electrical tables under conditions of internal self-heating where TJ > TA. Absolute Maximum Ratings indicate junction temperature limits beyond which the device may be permanently degraded, either mechanically or electrically. (2) Limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlations using statistical quality control (SQC) method. (3) Typical values represent the most likely parametric norm at the time of characterization. Actual typical values may vary over time and will also depend on the application and configuration. The typical values are not tested and are not ensured on shipped production material. (4) Offset voltage temperature drift is determined by dividing the change in VOS at the temperature extremes by the total temperature change. (5) This parameter is ensured by design and/or characterization and is not tested in production. (6) Positive Bias Current corresponds to current flowing into the device. Spec does not include input signal dependent currents on the positive input of approximately Vsense / 5K Ω due to topology feedback action. 6 Submit Documentation Feedback Copyright © 2010–2014, Texas Instruments Incorporated Product Folder Links: LMP8640 LMP8640-Q1 LMP8640HV |
