TFA9881 Datasheet - NXP Semiconductors

TFA9881 3.4 W PDM input class-D audio amplifier

The TFA9881 is a mono, filter-free class-D audio amplifier in a 9-bump WLCSP (Wafer Level Chip-Size Package) with a 400 m pitch. The digital input interface is an over-sampled Pulse Density Modulated (PDM) bit stream. The TFA9881 receives audio and control settings via this interface. Dedicated sil.

TFA9881 Features

* Small outline WLCSP9 package: 1.3  1.3  0.6 mm

* Wide supply voltage range (fully operational from 2.5 V to 5.5 V)

* High efficiency (90 %, 4 /20 H load) and low power dissipation

* Quiescent power:

* 6.5 mW (VDDD = 1.8 V, VDDP = 3.6 V, 4 /20 H load, fclk = 2.048 MHz)
