2.5-W MONO FILTER-FREE CLASS-D AUDIO POWER AMPLIFIERDESCRIPTION
The TPA2031D1 is a 2.5-W high efficiency filter-free
class-D Audio Power Amplifier in a 1,45 mm 1,45
mm wafer chip scale package (WCSP) that requires
only three external components.
Features like 88% efficiency, 75-dB PSRR,
mproved RF-rectification immunity, and 8 mm 2
total
PCB area make the TPA2031D1 class-D amp ideal
for cellular handsets. 32 ms start-up time allows the
TPA2031D1 to share the same GPIO
enable/shutdown control as the CODEC without
passing through the CODEC turn-on pop.
In cellular handsets, the earpiece, speaker phone,
and melody ringer CAN each be driven by the
TPA2031D1. The TPA2031D1 allows independent
gain while summing signals from separate sources,
and has a low 36 V noise floor, A-weighted. By Texas Instruments
