description
The TPA152 is a stereo audio power amplifier capable of less than 0.1% THD+N at 1 kHz when delivering
75 mW per channel into a 32-Ω load. THD+N is less than 0.2% across the audio band of 20 to 20 kHz. For
10 kΩ loads, the THD+N performance is better than 0.005% at 1 kHz, and less than 0.01% across the audio
band of 20 to 20 kHz.
The TPA152 is ideal for use as an output buffer for the audio CODEC in PC systems. It is also excellent for use
where a high-performance head phone/line-out amplifier is needed. Depop circuitry is integrated to reduce
transients during power up, power down, and mute mode.
Amplifier gain is externally configured by means of two resistors per input channel and does not require external
compensation for settings of 1 to 10. The TPA152 is packaged in the 8-pin SOIC (D) package that reduces board
space and facilitates automated assembly.
