TLV320AIC1110GQER

Product Summary

The TLV320AIC1110GQER is a PCM CODEC. The TLV320AIC1110GQER provides extended gain and attenuation flexibility for transmit, receive, and sidetone paths. A differential earphone output is capable of driving speaker loads as low as 8 Ω for use in speaker phone applications. The single tone function on the TLV320AIC1110GQER generates a single tone output of up to 8 kHz. The resolution of the DTMF tone is also selectable to 7.8125 Hz, 15.625 Hz, or 31.25 Hz through the interface control. The analog switch provides more control capabilities for voice-band audio processor (PCM codec). The applications of the TLV320AIC1110GQER include Digital Handset, Digital Headset, Cordless Phones, Digital PABX, Digital Voice Recording.
