Three Fixed Gain Versions
The TPA2032D1 (2V/V gain), TPA2033D1 (3V/V
gain), and TPA2034D1 (4V/V gain) are 2.75-W high
TPA2032D1 has a gain of 2 V/V (6dB)
efficiency filter-free class-D audio power amplifiers,
TPA2033D1 has a gain of 3 V/V (9.5dB)
each in an approximately 1.5-mm × 1.5-mm wafer
TPA2034D1 has a gain of 4 V/V (12dB)
