The HWD2190 is an audio power amplifier primarily designedfor demanding applicaTIons in mobile phones and other portablecommunicaTIon device applicaTIons. It is capable ofdelivering 1 watt of conTInuous average power to an 8Ω BTLload with less than 1% distortion (THD+N) from a 5VDCpower supply.audio power amplifiers were designed specifically toprovide high quality output power with a minimal amount ofexternal components. The HWD2190 does not require outputcoupling capacitors or bootstrap capacitors, and therefore isideally suited for mobile phone and other low voltage applicationswhere minimal power consumption is a primary requirement.The HWD2190 features a low-power consumption shutdownmode, which is achieved by driving the shutdown pin withlogic low. Additionally, the HWD2190 features an internal thermalshutdown protection mechanism.The HWD2190 contains advanced pop & click circuitry whicheliminates noises which would otherwise occur duringturn-on and turn-off transitions.The HWD2190 is unity-gain stable and can be configured by external gain-setting resistors.
