– Optimized PWM Output Stage Eliminates
LC Output Filter
The TPA2010D1 (sometimes referred to as
– Internally Generated 250-kHz Switching
TPA2010) is a 2.5-W high efficiency filter-free class-D
Frequency Eliminates Capacitor and
audio power amplifier (class-D amp) in a 1,45 mm ×
1,45 mm wafer chip scale package (WCSP) that
Resistor
requires only three external components.
– Improved PSRR ( – 75 dB) and Wide Supply
Voltage (2.5 V to 5.5 V) Eliminates Need for
Features like 88% efficiency, – 75-dB PSRR,
a Voltage Regulator improved RF-rectification immunity, and 8 mm

– Fully Differential Design Reduces RF
amp ideal for cellular handsets. A fast start-up time of
Rectification and Eliminates Bypass
1 ms with minimal pop makes the TPA2010D1
Capacitor
(TPA2010) ideal for PDA applications.
– Improved CMRR Eliminates Two Input
In cellular handsets, the earpiece, speaker phone,
Coupling Capacitors
and melody ringer can each be driven by the
• Wafer Chip Scale Packaging (WCSP)
TPA2010D1. The TPA2010D1 allows independent

gain while summing signals from seperate sources,
and has a low 36 μ V noise floor, A-weighted.
– NanoStar™ SnPb (YEF)
