• Maximum Battery Life and Minimum Heat
– Efficiency With an 8-Ω Speaker:
3 Description
– 88% at 400 mW
The TPA2006D1 device is a 1.45-W high efficiency
– 80% at 100 mW
filter-free class-D audio power amplifier in a 3 mm × 3
mm VSON package that requires only three external
– 2.8-mA Quiescent Current
components. The SHUTDOWN pin is fully compatible
– 0.5-μA Shutdown Current
with 1.8-V logic GPIO, such as are used on low-
• SHUTDOWN Pin has 1.8-V Compatible
power cellular chipsets.
Thresholds
Features like 88% efficiency, –75-dB PSRR,
• Capable of Driving an
improved RF-rectification immunity, and small total
8-Ω Speaker (2.5 V ≤ V
DD
≤ 5.5 V) and a
PCB footprint make the TPA2006D1 device ideal for
4-Ω Speaker (2.5 V ≤ V
DD
≤ 4.2 V)
cellular handsets. A fast start-up time of 1 ms with
minimal pop makes the TPA2006D1 device ideal for
• Only Three External Components
PDA applications.
– Optimized PWM Output Stage Eliminates LC
In cellular handsets, the earpiece, speaker phone,
Output Filter
and melody ringer can each be driven by the
– Internally Generated 250-kHz Switching
TPA2006D1 device. The TPA2006D1 device allows
Frequency Eliminates Capacitor and Resistor
independent gain while summing signals from
– Improved PSRR (–75 dB) and Wide Supply
separate sources, and has a low 36-μV noise floor,
Voltage (2.5 V to 5.5 V) Eliminates Need for a
A-weighted.
Voltage Regulator
The TPA2006D1 device has short-circuit and thermal
