    Claiming a 30% lower power consumption than ground-referenced Class-AB devices, the TPA6140A2 and TPA6141A2 25-mW, Class-G, DirectPath stereo headphone amplifiers adjust their voltage supplies to the audio signal to minimize power dissipation. The amplifiers employ the company’s DirectPath technology, which eliminates the need for large dc-blocking capacitors at the amplifier outputs. They also integrate pop-suppression circuitry and specify a power supply rejection of greater than 100 dB and a SNR of 100 dB. Other features include a 0.6-mA/channel quiescent current, power output of 5 mW/channel into a 32-Ohm load, and a total supply current under 5 mA. The TPA6140A2 provides a variable gain range of -59 dB to +4 dB programmable via a 32-step I2C volume control and the TPA6141A2 offers two fixed gain settings of 0 dB and +6 dB. The TPA6140A2 is available now in a 1.6 mm x 1.6 mm WCSP package, priced at $0.95 each/1,000. The TPA6141A2 will be available later this year.
