TPA6111A2D Description

Short technical summary and product information.

The TPA6111A2D from Texas Instruments is a stereo audio power amplifier capable of delivering 150 mW of continuous RMS power per channel into 16-Ω loads. This amplifier is suitable for applications requiring high-quality audio output with minimal distortion.

Key electrical characteristics include operation specified for 3.3-V and 5-V power supplies, with THD+N as low as 0.03% at 1 kHz when driving a 16-Ω load from 5 V. For 32-Ω loads, THD+N is further reduced to less than 0.02% at 1 kHz. The amplifier gain is externally configurable via resistors, simplifying design and eliminating the need for external compensation for gain settings between 0 and 20 dB.

Designed for ease of integration, the TPA6111A2D features internal midrail generation and pop-reduction circuitry. It also includes thermal and short-circuit protection for enhanced reliability. The device is available in surface-mount packages, including SOIC and MSOP (PowerPAD), making it suitable for space-constrained designs.

This amplifier is pin-compatible with other Texas Instruments audio amplifiers like the TPA122, LM4880, and LM4881 in the SOIC package, offering flexibility in component selection and board design.
