TPA6132 Description

Short technical summary and product information.

The TPA6132 from Texas Instruments is a DirectPath™ stereo headphone amplifier that simplifies designs by eliminating the need for external DC-blocking output capacitors. Its patented technology biases outputs at 0V, providing excellent low-frequency fidelity and active click and pop suppression during power transitions.

 

This amplifier features fully differential or single-ended inputs with built-in resistors to reduce component count and improve system noise performance. It delivers a constant maximum output power from a 2.3 V to 5.5 V supply, simplifying designs for preventing acoustic shock. The device offers selectable gain settings of -6 dB, 0 dB, 3 dB, and 6 dB.

 

With a typical supply current of 2.1 mA, the TPA6132 is suitable for portable applications. It boasts high power supply noise rejection, with 100 dB PSRR at 217 Hz and 90 dB PSRR at 10 kHz, along with improved RF noise immunity. The amplifier includes short-circuit and thermal-overload protection, and its outputs are protected with ±8 kV HBM ESD protection.

 

The TPA6132 is available in a compact 16-pin, 3 mm x 3 mm WQFN package, making it ideal for space-constrained designs. It operates within an ambient temperature range of -40°C to 85°C.
