The TAS5613APHDR is an audio amplifier. It is a part of Texas Instrument’s TAS56xx portfolio and a cost-effective solution for automotive audio applications. This device utilizes Texas Instrument’s proprietary High Dynamic Range (HDR) technology to deliver high quality sounds throughout the car or other system.

The TAS5613APHDR delivers an efficient audio solution by combining an integrated Adaptive Class-H (ACH) amplifier with a Class-D digital driver to yield a high dynamic range, low ripple output. This combination of technologies helps the amplitude of the signal to reach the desired audible levels without any distortion.

The amplifier is designed for applications such as HIFI, audio systems, automotive multimedia systems, sound and voice control systems. It is available in Channels/Bands of 2×6/8-Stereo Class-D with low power output (250mW for each Channel) and an audio performance most suited for high-fidelity (Hi-Fi) audio systems for automotive and consumer applications.

The TAS5613APHDR has the ability to drive two 6 or 8 mono speaker systems with exceptional power efficiency, featuring a peak current control with adaptive drive circuitry. The built-in adaptive dynamic biasing circuitry ensures that the device offers both high efficiency and low thermal output. The integrated Adaptive Class-H amplifier ensures that the power to the speaker is regulated to deliver a low distortion signal, while managing thermal power dissipation.

The core of the TAS5613APHDR is the on-chip High Dynamic Range (HDR) amplifier. The prototype chips are fabricated using the TSMC 0.18um CMOS process and are optimized to maximize the signal-to-noise ratio while managing power efficiency and increased range. The HDR technology was invented by Texas Instruments in order to enable more efficient and accurate sound reproduction.

The core output power of the TAS5613APHDR ranges from 1.8W-6W and can be used with both balanced and unbalanced loads. The device also features an adjustable gain setting and an adjustable operating temperature range with excellent control over dynamic temperature range. The device also enables continuous adjustment of current limiting, quiescent current and peak current limit.

The TAS5613APHDR operates at a wide power supply range, from 3.3V to 15V. The device features an Auto-Mute/Stereo Mode feature, which enables the amplifier to operate in a power efficient mode when no signal is present and switch back to the stereo mode when an input signal is detected. This feature helps to conserve power when no audio is being reproduced.

The signal-to-noise ratio of the TAS5613APHDR is 100 dB, which is the highest in the industry. The device also incorporates Texas Instrument’s proprietary thermally managed device which helps to protect the device from high temperature variance. It is ideal for a high power application due to its low ripple, low distortion and low noise performance.

Overall, the TAS5613APHDR is an audio amplifier that provides higher fidelity sounds in automotive and consumer applications. With its high dynamic range and excellent signal-to-noise ratio, it is ideal for applications that require excellent sound reproduction and require an efficient device to power them. Its compact size and low power consumption also make it perfect for use in mobile and battery-powered applications.
