TPA2032D1 2.75-W FIXED GAIN MONO FILTER-FREE CLASS-D AUDIO POWER AMPLIFIER

TPA2032D1 2.75-W FIXED GAIN MONO FILTER-FREE CLASS-D AUDIO POWER AMPLIFIER

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 TPA2010.
