TPA2033D1

illustrate

The TPA2032D1 (2V/V gain), TPA2033D1 (3V/V gain), and TPA2034D1 (4V/V gain) are 2.75-W high-efficiency filterless Class D audio power amplifiers, each approximately 1.5 mm × 1.5 mm wafer chip scale package (WCSP) requiring only one external component. The pins are the same TPA2010D1 except for the external gain setting TPA2010D1 the required input resistance is divided into fixed gain TPA203xD1 family synthesis.

Features such as -75dB PSRR and a very small PCB package (WCSP package amplifier plus single decoupling capacitor) improve RF rectification immunity ideal for the TPA203xD1 home on wireless handheld devices. The fast boot time of 3.2 ms with minimal popularity makes the TPA203xD1 ideal for PDA applications.
