6 / 28 page LM4990 SNAS184E – DECEMBER 2002 – REVISED MAY 2013 www.ti.com Electrical Characteristics VDD = 3V (1) (2) The following specifications apply for the circuit shown in Figure 1, unless otherwise specified. Limits apply for TA = 25°C. LM4990 Units Symbol Parameter Conditions (Limits) Typical(3) Limit(4)(5) VIN = 0V, Io = 0A, No Load 2 7 mA (max) IDD Quiescent Power Supply Current VIN = 0V, Io = 0A, 8Ω Load 3 9 mA (max) ISD Shutdown Current VSD = VSD Mode (6) 0.1 2.0 µA (max) VSDIH Shutdown Voltage Input High VSD MODE = VDD 1.1 V VSDIL Shutdown Voltage Input Low VSD MODE = VDD 0.9 V VSDIH Shutdown Voltage Input High VSD MODE = GND 1.3 V VSDIL Shutdown Voltage Input Low VSD MODE = GND 1.0 V VOS Output Offset Voltage 7 50 mV (max) ROUT 9.7 k Ω (max) Resistor Output to GND(7) 8.5 7.0 k Ω (min) (8 Ω) THD+N = 1% (max); f = 1kHz 425 mW Po Output Power (4 Ω) THD+N = 1% (max); f = 1kHz 600 mW TWU Wake-up time 75 ms THD+N Total Harmonic Distortion+Noise Po = 0.25Wrms; f = 1kHz 0.1 % +N Vripple = 200mV sine p-p 62 (f = 217Hz) PSRR Power Supply Rejection Ratio 55 dB (min) Input terminated with 10 Ω 68 (f = 1kHz) (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is intended to be functional but specific performance is not ensured. 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. (2) All voltages are measured with respect to the ground pin, unless otherwise specified. (3) Typicals are measured at 25°C and represent the parametric norm. (4) Limits are specified to 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. (7) RROUT is measured from the output pin to ground. This value represents the parallel combination of the 10kΩ output resistors and the two 20k Ω resistors. 6 Submit Documentation Feedback Copyright © 2002–2013, Texas Instruments Incorporated Product Folder Links: LM4990 |
