2.6W MONO FILTER-FREE CLASS-D

DESCRIPTION

FEATURES

The A2327 is a 2.6W high efficiency filter-free class-D

audio power amplifier that requires only three

external components.



Efficiency With an 8Ω Speaker:

88% @ 400mW

80% @ 100mW

Features like 88% efficiency, −75dB PSRR, and

improved RF-rectification immunity make the A2327

ideal for cellular handsets. In cellular handsets, the

earpiece, speaker phone, and melody ringer can

each be driven by the A2327.



3.8mA Quiescent Current

0.4μA Shutdown Current

Optimized PWM Output Stage Eliminates LC

Output Filter



Internally

Generated

250kHz

Switching

Frequency Eliminates Capacitor and Resistor

Improved PSRR (−75dB) and Wide Supply

Voltage (2.5V to 5.5V) Eliminates Need for a

Voltage Regulator

The A2327 is available in MSOP8, SOP8 and

DFN8 packages.



Fully

Differential Design Reduces
