LM4667MMBD/NOPB
| Filterless High Efficiency 1.3W Switching Audio Amplifier | Full production
Lead Free (RoHS)
|
| $100.00 each | 1 |
| The LM4667 is a fully integrated 1.3W, single-supply high efficiency (Class D) switching audio amplifier. It features an innovative modulator that eliminates the LC output filter used with typical switching amplifiers. The LM4667 processes analog inputs with a delta-sigma modulation technique that lowers output noise and THD when compared to conventional pulse width modulators.
This LM4667MMBD is an evaluation board designed to ease the evaluation and effort during the development of a circuit using the LM4667MM. It is an easy to use stand-alone board that requires power and GND, an input signal and an output load.

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.
