What are the key features of TLV320AIC1106PW?
- Integrated µ-law PCM codec with 13-bit linear coding eliminates the need for a separate ADC/DAC pair in voice telephony designs
- Built-in microphone preamplifier and speaker driver reduce external component count for complete voice channel implementation
- Differential analog input rejects common-mode noise, improving SNR in electrically noisy handset and intercom environments
- On-chip transmit and receive filters comply with telephony mask requirements, simplifying certification of end equipment
What is TLV320AIC1106PW used for?
The TLV320AIC1106PW is designed for voice-band applications such as PSTN telephone handsets, VoIP ATAs, and industrial intercoms where a single PCM channel with µ-law coding is required. Its integrated microphone amplifier, codec, and speaker driver allow designers to build a complete voice front end with minimal external components. The device is also suited for embedded voice recording and playback modules in access control systems and announcement terminals.

Frequently Asked Questions
What companding law does the TLV320AIC1106PW support?
The TLV320AIC1106PW supports µ-law (mu-law) companding as defined by ITU-T G.711, which is the standard encoding used in North American and Japanese telephony networks. This makes it directly compatible with PSTN line cards and VoIP gateway voice channels without additional processing.
Does the TLV320AIC1106PW include a speaker driver?
Yes, the device integrates a speaker driver capable of driving an earpiece or small loudspeaker directly, eliminating the need for a discrete audio amplifier IC and reducing the overall component count and PCB area in telephone handset and intercom designs.
What type of analog input does the TLV320AIC1106PW use?
The TLV320AIC1106PW uses a differential analog input for the microphone path, which provides superior common-mode noise rejection compared to single-ended inputs. This is especially beneficial in handsets where the microphone cable can pick up noise from nearby digital circuitry.
What package does the TLV320AIC1106PW come in and how many pins does it have?
The TLV320AIC1106PW is available in a 20-pin TSSOP (PW suffix) package. The TSSOP format offers a compact surface-mount footprint suitable for modern PCB designs requiring high component density in telephone and communication equipment.
What is the gain tolerance specification of the TLV320AIC1106PW?
The TLV320AIC1106PW has a maximum gain tolerance of 1.2 dB, ensuring consistent voice level across production units without manual calibration. This tight specification is important for telecommunications equipment that must meet network-interface transmission level requirements.
