LM4811 Units Parameter Test Conditions (Limits) Typ(3) Limit (4) IDD Supply Current VIN = 0V, IO = 0A 1.1 mA ISD Shutdown Current VIN = 0V 0.3 µA VOS Output Offset Voltage VIN = 0V 4.0 mV Po Output Power 0.1% THD+N; f = 1kHz RL = 16Ω 40 mW RL = 32Ω 28 mW THD+N Total Harmonic Distortion PO = 25mW, RL = 32Ω 0.5 % f = 20Hz to 20kHz PSRR Power Supply Rejection Ratio CB = 1.0µF, VRIPPLE = 100mVPP 60 dB f = 217Hz VIH (CLOCK, UP/DN, SHUTDOWN) 1.4 V (min) Input Voltage High VIL (CLOCK, UP/DN, SHUTDOWN) 0.4 V (max) Input Voltage Low Digital Volume Range Input referred minimum gain −33 dB Input referred maximum gain +12 dB Digital Volume Stepsize All 16 discrete steps 3.0 dB Stepsize Error All 16 discrete steps ±0.3 dB Channel −to−Channel Volume All gain settings from 0.15 dB Tracking Error −33dB to +12dB Shutdown Attenuation Shutdown mode active −100 dB (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. (2) All voltages are measured with respect to the ground pin, unless otherwise specified. (3) Typical specifications are specified at +25°C and represent the most likely parametric norm. (4) Tested limits are ensured to TI's AOQL (Average Outgoing Quality Level). Datasheet min/max specification limits are ensured by design, test, or statistical analysis. 4 Submit Documentation Feedback Copyright © 2000–2013, Texas Instruments Incorporated Product Folder Links: LM4811 |
