DESCRIPTION

The TPA2032D1 (2V/V gain), TPA2033D1 (3V/V

gain), and TPA2034D1 (4V/V gain) are 2.75-W high

efficiency filter-free class-D audio power amplifiers,

each in an approximately 1.5-mm ´ 1.5-mm wafer

chip scale package (WCSP) that requires only one

external component. The pinout is the same as the

TPA2010D1 except that the external gain setting

input resistors required by the TPA2010D1 are

integrated into the fixed gain TPA203xD1 family.

Features like –75dB PSRR and improved

RF-rectification immunity with a very small PCB footprint (WCSP amplifier plus single decoupling

cap) make the TPA203xD1 family ideal for wireless

handsets. A fast start-up time of 3.2 ms with minimal

pop makes the TPA203xD1 family ideal for PDA

applications.

In wireless handsets, the earpiece, speaker phone,

and melody ringer can each be driven by a

TPA203xD1. The TPA203xD1 family has a low

27-mV noise floor, A-weighted.
