TLV320AIC34IZASR

Product Summary

The TLV320AIC34IZASR is a low-power four-channel audio codec with four-channel headphone amplifier, as well as multiple inputs and outputs programmable in single-ended or fully differential configurations. Extensive register-based power control is included, enabling four-channel 48-kHz DAC playback as low as 15 mW from a 3.3-V analog supply, making it ideal for portable battery-powered audio and telephony applications. The applications of the TLV320AIC34IZASR include digital cameras, smart cellular phones.
