Fully Differential Design Reduces RF Rectification and Eliminates Bypass Capacitor
CMRR (69 dB)Eliminates Two Input Coupling Capacitors
Thermal and ShortCircuit Protection
Pinout Very Similar to TPA2010D1
Wafer Chip Scale Packaging (WCSP)
NanoFree LeadFree (PbFree: YZF)
APPLICATIONS
Ideal for Wireless Handsets, PDAs, and other mobile devices
Description
The TPA2032D1 (2V/V gain), TPA2033D1 (3V/V gain), and TPA2034D1 (4V/V gain) are 2.75W high efficiency filterfree classD audio power amplifiers, each in an approximately 1.5mm × 1.5mm 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 RFrectification immunity with a very small PCB footprint (WCSP amplifier plus single decoupling cap) make the TPA203xD1 family ideal for wireless handsets. A fast startup 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 27µV noise floor, Aweighted.
