Texas Instruments Incorporated (TI) has introduced audio codecs and digital-to-analog converters (DACs) for eBooks, mobile Internet devices and portable navigation devices. The highly integrated codecs (TLV320AIC3100, TLV320AIC3110, TLV320AIC3111, TLV320AIC3120) and DACs (TLV320DAC3101, TLV320DAC3100, TLV320DAC3120) reduce component count and system cost compared to discrete implementations and support enhanced audio features to improve the consumer's listening experience. In addition, the devices are pin-to-pin and software compatible, reducing hardware and software development to accelerate time-to-market.
The devices integrate Class-D speaker amplifiers with up to 2.5 W of output power, eliminating the need for multiple resistors and capacitors between the codec and speaker amp for reduced component count and system cost when compared to discrete implementations. The products support analog and digital microphones. Customers using digital microphones in conjunction with these devices can achieve up to 10-dB or greater system-level noise immunity versus competitive solutions, critical for a high quality audio experience in portable designs. Part of TI’s complete system solution for eBooks including applications processors and wireless connectivity, display, power and battery management integrated circuits (ICs).
