4 / 20 page LM4929 SNAS293B – DECEMBER 2004 – REVISED APRIL 2013 www.ti.com Electrical Characteristics VDD = 5V (1) (2) The following specifications apply for VDD = 5V, RL = 16Ω, and CB = 4.7µF unless otherwise specified. Limits apply to TA = 25°C. Pin 3 connected to GND (3). Symbol Parameter Conditions LM4929 Units (Limits) Typ(4) Limit(5) IDD Quiescent Power Supply Current VIN = 0V, IO = 0A 2 5 mA (max) ISD Shutdown Current VSHUTDOWN = GND 0.1 2.0 µA(max) VSDIH Shutdown Voltage Input High 1.8 V VSDIL Shutdown Voltage Input Low 0.4 V THD = 1%; f = 1 kHZ PO Output Power RL= 16Ω 80 mW RL = 32Ω 80 VNO Output Noise Voltage BW = 20Hz to 20kHz, A-weighted 10 µV PSRR Power Supply Rejection Ratio VRIPPLE = 200mV sine p-p 65 dB (1) All voltages are measured with respect to the GND 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) Pin 3 (NC) should be connected to GND for proper part operation. (4) Typicals are measured at 25°C and represent the parametric norm. (5) Limits are specified to Texas Instruments' AOQL (Average Outgoing Quality Level). Electrical Characteristics VDD = 3.0V (1) (2) The following specifications apply for VDD = 3.0V, RL = 16Ω, and CB = 4.7µF unless otherwise specified. Limits apply to TA = 25°C. Pin 3 connected to GND (3).
