Product Description
- The LM4670SD is a fully integrated single-supply high efficiency switching Audio Amplifier. It features an innovative modulator that eliminates the LC output filter used with typical switching amplifiers. Eliminating the output filter reduces external component count, simplifies circuit design and reduces board area. The LM4670 processes analog inputs with a delta-sigma modulation technique that lowers output noise and THD when compared to conventional pulse width modulators. The LM4670 is designed to meet the demands of mobile phones and other portable communication devices. Operating on a single 5V supply, it is capable of driving a 4R speaker load at a continuous average output of 2.3W with less than 1% THD+N. Its flexible power supply requirements allow operation from 2.4 to 5.5V. The LM4670 has high efficiency with speaker loads compared to a typical class AB amplifier.
- No output filter required for inductive transducers
- Externally configurable gain
- Minimum external components
- Click and pop suppression circuitry
- Micro-power shutdown mode
- Short-circuit protection
- 1.35ms (typical) Very fast turn on time
- 2kV ESD susceptibility
- Green product and no Sb/Br
