` Wafer Chip Scale Packaging (WCSP)
NanoFree™ Lead-Free (Pb-Free: YZF)

(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under ecommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device eliability.
(2) The output pins Vo and Vo+ are tolerant to 1.5KV HBM ESD

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 of TPA2032D1 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 of TPA2032D1 like 75dB PSRR and improved fRoFo-trpercintitfic(aWtioCnSPimammupnliitfyierwipthlusa svinegryle sdmeaclolupPlCinBg 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.
