Overview
The TPA152D is a stereo audio power amplifier manufactured by Texas Instruments, designed for single-supply operation. It belongs to the Class AB topology and delivers 75mW per channel into a 32-ohm load when powered by a 5V supply. The device operates within a voltage range of 4.5V to 5.5V and supports an ambient temperature range from -40°C to +85°C. It is housed in an 8-SOIC surface-mount package with dimensions of 4.9 x 3.91 x 1.58mm.
Feature Summary
- Integrated protection mechanisms including pop-and-click suppression, mute functionality, short-circuit protection, and thermal shutdown.
- Designed for efficient single-supply operation suitable for portable battery-powered applications.
- Delivers stereo output capability optimized for driving low-impedance loads such as headphones.
Applications
- Headphone amplification circuits
- Portable electronic devices requiring stereo audio output
- Battery-operated consumer electronics
Procurement Notes
Verify the specific suffix 'D' indicates the SOIC-8 package variant. Confirm RoHS compliance status through official datasheets or manufacturer declarations. Ensure moisture sensitivity level (MSL 1) handling requirements are met during storage and assembly processes.
Selection Notes
Select this component for designs requiring a compact stereo amplifier solution with built-in protection features. Consider the 8-SOIC footprint for PCB layout constraints. Evaluate the 75mW output capability against the specific impedance and volume requirements of the target audio transducers.
Part Context
The TPA152D is part of Texas Instruments' portfolio of linear audio amplifiers. It serves as a stereo counterpart to mono variants like the TPA701D, offering dual-channel performance in a similar small outline integrated circuit format. This series targets cost-sensitive portable markets.
Replacement Considerations
Check for pin-compatible alternatives within the TI TPA series. Verify that substitute components match the 8-SOIC package and support the required 4.5V to 5.5V operating voltage range without altering system performance.
