Low-power part integrates stereo headphone amplifier and mono Class D speaker amplifier

The TLV320AIC3107 codec is claimed by the company to reduce board area and cost by 20% over discrete solutions by integrating a stereo headphone amplifier and mono Class D speaker amplifier.

The device consumes just 15 mW at 48 kHz and has a 3.3-V analog supply. It also features a stereo 8 to 96-ksample/s D/A converter with 97-dB SNR and 8 to 96-ksample/s A/D converter with 92-dB SNR.

In addition, its mono Class D speaker amplifier can drive 1 W into an 8-Ω load. Offered in a 5 x 5-mm QFN-40 package, the TLV320AIC3107 provides multiple inputs and outputs that are programmable in single-ended or fully differential configurations. ($3.85 ea/1,000 — available now.)
