LM4802B
Overview
The LM4802B integrates a Boost Converter with an Audio Power Amplifier to drive Ceramic Speakers in portable applications. When powered by a 3V supply, it is capable of forcing 12Vp-p across a 2µF + 30Ω bridge-tied-load (BTL) with less than 1% THD+N.
- Pop & click circuitry eliminates noise during turn-on and turn-off transitions
- Low, 2µA (max) shutdown current
- Low, 12mA (typ) quiescent current
- 12Vp-p mono BTL output, load = 2µF + 30Ω, VDD = 3V
- Short circuit protection
- Unity-gain stable
- External gain configuration capability
