LM4809LQBD
| LM4809 Dual 105mW Headphone Amplifier with Active-Low Shutdown Mode | Full production
|
| $200.00 each | 1 |
| The LM4809 is a dual audio power amplifier capable of delivering 105mW per channel of continuous average power into a 16Ω load with 0.1% (THD+N) from a 5V power supply.
This LM4809LQBD is an evaluation board designed to ease the evaluation and effort during the development of a circuit using the LM4809LQ. It is an easy to use stand-alone board that requires power and GND, an input signal and an output load.
Features:
- Active-low shutdown mode
- "Click and Pop" reduction circuitry
- Low shutdown current
- LLP, surface mount package
- No bootstrap capacitors required
- Unity-gain stable
Applications:
- Headphone Amplifier
- Personal Computers
- Microphone Preamplifier
- PDA's
- Cellular phones
Contents:
- Fully Assembled LM4809LQ Evaluation Board
- Instructions for where to locate and download the datasheet
Please note: application information and board layout can be found in datasheet |

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR.
The Long Term Failure Rates were calculated
at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress
temperature of 150°C to an application temperature of 55°C.
