Designers of portable systems can benefit from extended playback time enabled by two new 25 mW Class-G, DirectPath stereo headphone amplifiers from Texas Instruments, which adjust their voltage supplies to the audio signal to minimise power dissipation.
The amplifiers feature TI’s field-proven DirectPath technology, which eliminates the need for large DC-blocking capacitors at the amplifier outputs to give designers additional board space and allow consumers to enjoy greater low-frequency audio fidelity. In addition, the TPA6140A2 and TPA6141A2 include built-in pop suppression circuitry, which completely eliminates disturbing pop noise when the amplifier powers on, to enable a seamless audio experience. Power supply rejection of greater than 100 dB and differential inputs improve noise rejection, while the 100 dB signal-to-noise ratio (SNR) improves the signal quality to deliver crystal clear audio.
These amplifiers consume only 0,6 mA quiescent current per channel and deliver 5 mW/channel into a 32 Ω load, while keeping the total supply current below 5 mA, to extend battery life. The TPA6140A2 provides a variable gain range of
-59 dB to +4 dB programmable via a 32-step I²C volume control to maximise design flexibility. The TPA6141A2 offers two fixed gain settings of 0 dB and +6 dB for customers who require less flexibility. A separate SGND pin reduces ground loop noise when interfacing with a non-headphone accessory.
