4 / 27 page LM4889 SNAS157H – APRIL 2002 – REVISED MAY 2013 www.ti.com Electrical Characteristics VDD = 5V (1)(2) (continued) The following specifications apply for VDD = 5V, AV = 2, and 8Ω load unless otherwise specified. Limits apply for TA = 25°C. LM4889 Units Symbol Parameter Conditions (Limits) Typical(3) Limit(4)(5) Vripple = 200mV sine p-p fripple = 217Hz 62 dB fripple = 1kHz 66 dB PSRR Power Supply Rejection Ratio Vripple = 200mV sine p-p Input Floating 75 68 dB Electrical Characteristics VDD = 3.3V (1) (2) The following specifications apply for VDD = 3.3V, AV = 2, and 8Ω load unless otherwise specified. Limits apply for TA = 25°C. LM4889 Units Symbol Parameter Conditions (Limits) Typical(3) Limit(4)(5) VIN = 0V, Io = 0A, no Load 3.5 7 mA (max) IDD Quiescent Power Supply Current VIN = 0V, Io = 0A, with BTL Load 4.5 7 mA (max) ISD Shutdown Current Vshutdown = GND (6) 0.01 2 µA (max) VSDIH Shutdown Voltage Input High 1.2 V (min) VSDIL Shutdown Voltage Input Low 0.4 V (max) Po Output Power THD = 1% (max); f = 1kHz 0.4 W THD+N Total Harmonic Distortion+Noise Po = 0.25Wrms; f = 1kHz 0.1 % Vripple = 200mV sine p-p PSRR Power Supply Rejection Ratio fripple = 217Hz 60 dB fripple =1kHz 62 dB (1) All voltages are measured with respect to the ground pin, unless otherwise specified. (2) 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 ensure 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. (3) Typicals are measured at 25°C and represent the parametric norm. (4) Limits are specified to TI's AOQL (Average Outgoing Quality Level). (5) Datasheet min/max specification limits are specified by design, test or statistical analysis. (6) For DSBGA only, shutdown current is measured in a Normal Room Environment. Exposure to direct sunlight will increase ISD by a maximum of 2µA. Electrical Characteristics VDD = 2.6V (1) (2) The following specifications apply for VDD = 2.6V, AV = 2, and 8Ω load unless otherwise specified. Limits apply for TA = 25°C.
