75-mW hi-fi low-voltage audio power amplifier

Product Features

Ultra-low THD+N: < 0.005% at 1 kHz
75-mW stereo output drive
Internal mid-rail generator
Depop circuitry
Pin compatible with TPA302
Characterized for operation from –40°C to 85°C

The TPA152 is a low-voltage audio power amplifier designed to drive stereo headphones. This amplifier delivers 75-mW stereo to a 32- load with less than 0.01% THD+N across the entire audio frequency band. Its hi-fi sound quality makes it well suited for applications including:

Portable CD players
Notebook computers
Voice recorders
Headphone amplifiers
Output buffer for audio CODECs in PCs

The TPA152 also features an integrated mid-rail generator. This circuitry minimizes component count by internally biasing the reference voltage.

The need for an external voltage divider is eliminated, saving time, board space and money.

TI is a recognized leader in providing audio power amplifier (APA) solutions. Each APA provides a unique set of features applicable to multiple designs.

The TPA152 is available in an 8-pin SOIC package.
