TPA2011D1 3.2-W Mono Filter-Free Class-D Audio Power Amplifier With Auto-Recovering Short-Circuit Protection

1 Description
The TPA2011D1 is a 3.2-W high efficiency filter-freeclass-D audio power amplifier(class-D amp)in a1.21 mm x1.16 mm wafer chip scale:package(DSBGA)that requires onlythreeexternal

components.
Features like 95% efficiency, 86-dB PSRR, 1.5 mAquiescent current and improved RF immunity makethe TPA2011D1class-D amp ideal for cellularhandsets.A fast start-up time of 4 ms with no audibletum-on pop makes the TPA2011D1 ideal for PDAand smart-phone applications. The TPA2011D1allows independent gain while summing signals fromseparate sources, and has a low 20 uV noise floor.
