LM4985TMEVAL
| LM4985 Stereo 135mW Low Noise Headphone Amplifier with Selectable Capacitive Coupled or OCL Output and Digitally Controlled (I2C) Volume Control | Full production
|
| $175.00 each | 1 |
| The LM4985 is a stereo low noise headphone amplifier in a tiny 0.4mm pitch micro SMD package. The LM4985 is designed to meet the demands of mobile phones and other portable communication devices. It is capable of delivering 135 milliwatts of average power to a 16 ohm load with less than 1% distortion (THD+N) from a 5V DC power supply.
The LM4985TMEVAL is an evaluation board designed to ease evaluation and effort during the development of a circuit using the LM4985TM. The evaluation board comes with an I2C card and cable. It is an easy-to-use stand-alone board that requires power and GND, an I2C control signal, aninput signal and anoutput load.
Features:
- Tiny 12-lead 0.4mm pitch micro SMD
- Very low iddq (2.3mA cap-coupled, 3mA OCL at 5V)
- High output power (135mW into 16ohms at 5V)
- PSRR 77dB at 217Hz
- THD+N 0.02% cap-coupled at 5V (Pout = 100mA)
Applications:
- Mobile phones
- PDAs
- Portable electronic devices and accessories
- Toys
Contents:
- Fully Assembled LM4985TM Evaluation Board
- I2C interface card and cable
- Instructions for where to locate and download the 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.
