1.7 WATT AUDIO POWER AMPLIFIER

REV2.2 - JUL 2008 RELEASED, NOV 2019 UPDATED - - 1 - DESCRIPTION FEATURES The A2203 is a Class -AB audio power amplifier primarily designed for demanding mobile phone s and other portable communication devices. It is capable of delivering 1.1 watts of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a 5VDC power supply. Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. The A2203 does not require output coupling capacitors or bootstrap capacitors. The A2203 is ideally suited for mobile phone , and other low voltage applications where minimal power consumption is a primary requirement. The A2203 features a low -power consumption shutdown mode. To facilitate this, Shutdown may be enable by e ither logic high or low pending on mode selection. Driving the shutdown mode pin either high or low enable the shutdown pin to be driven in a likewise manner to enable shutdown. The A2203 contains advanced pop-click circuitry which eliminates noise, which would otherwise occur during turn-on and turn-off transitions. The A2203 is unity-gain stable and can be configured by external gain-setting resistors. The A2203 is available in MSOP8 and SOP8 packages  Ultra low shutdown current: 0.1uA (typ.)  Improved PSRR at 217 Hz & 1 kHz: 60dB  2.2V ~ 5.5V operation  Power output at 5.0V, 10%THD+N, 4Ω: 1.7W(typ.) (SOP8 package)  Power output at 5.0V, 1% THD+N, 8Ω: 1.1W (typ.)  2.2V ~ 5.5V operation  Unity-gain stable  External gain configuration capability  Improved circuitry eliminates pop -click noise during turn-on and turn-off transitions  No output coupling capacitors, snubber networks or bootstrap capacitors required  Available in MSOP8 and SOP8 Packages APPLICATION  Car Block Box  Wireless handsets  Portable electronic devices  PDAs, Handheld computers TYPICAL APPLICATION Figure 1
