Product details
Overview
TLV320AIC1106PWG4 from Texas Instruments is a single-chip PCM audio codec IC designed for voice-band telecommunication systems, performing A/D and D/A conversion, transmit/receive filtering, and volume control. It operates at 2.7–3.3 V, supports 13-bit linear or 8-bit µ-law companding, delivers 200 mW differential output into 8 Ω, and features 300 Hz–3.4 kHz passband for digital handsets and PABX terminals.
For engineers reviewing the TLV320AIC1106PWG4 datasheet, TLV320AIC1106PWG4 pinout, TLV320AIC1106PWG4 application, or TLV320AIC1106PWG4 equivalent, key selection criteria include its 20-pin TSSOP package, 2.048 MHz master clock requirement, differential microphone/earphone interfaces, programmable mute functions, and compliance with CCITT G.714 filter specifications.
Technical Context
The TLV320AIC1106PWG4 integrates a third-order sigma-delta analog modulator for transmit path and a second-order digital modulator/filter for receive path, both synchronized to a 2.048 MHz master clock. Its PLL locks to MCLK to generate internal clocks for digital filters and modulators, enabling fixed 8 kHz sampling rate via PCMSYNC.
Transmit and receive paths each employ digital filters meeting CCITT G.714 requirements, with selectable 13-bit linear (MSB-first, 13-bit words) or 8-bit µ-law (MSB-first, 8-bit words) PCM data formats. Volume control is implemented in linear mode using RXVOL[2:0] bits in the 16-bit PCMI word, offering −18 dB to +3 dB in 3-dB steps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 3.3 V - Enables direct integration into 3.3-V telecom and handset power rails without level-shifting. |
| Audio Bandwidth | 300 Hz to 3.4 kHz - Matches PSTN voice channel requirements per ITU-T G.712 and G.714 standards. |
| Output Power | 200 mW into 8 Ω (differential) - Drives low-impedance earphones directly without external amplification. |
| Idle Channel Noise | −80 dBm0p (transmit, µ-law), −90 dBm0 (receive, µ-law) - Meets telecom-grade signal integrity for voice clarity. |
| Sampling Rate | 8 kHz (fixed, derived from 2.048 MHz MCLK ÷ 256) - Ensures synchronous PCM frame alignment with E1/T1 infrastructure. |
| Power Consumption | 7 mA typical active, 30 µA in power-down - Supports battery-operated voice terminals with low standby leakage. |
| Crosstalk Attenuation | 70 dB (TX-to-RX and RX-to-TX, differential) - Prevents audible feedback or echo in full-duplex voice applications. |
Pinout & Package
TLV320AIC1106PWG4 uses a 20-terminal TSSOP (PW) package, 4.4 mm × 6.5 mm, 0.65 mm pitch, RoHS-compliant NIPDAU finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MICIN+, MICIN− | Differential microphone input | Accepts capacitively coupled mic signals; enables noise-rejecting front-end with externally set gain (23.5 dB typical). |
| EAROUT+, EAROUT− | Differential earphone output | Drives 8–32 Ω loads directly; suppresses clicks/pops and supports single-ended configuration if needed. |
| PCMI, PCMO, PCMSYNC | PCM serial interface | Supports standard 8/13-bit MSB-first PCM framing at 8 kHz; PCMSYNC = frame sync derived from MCLK. |
| MICMUTE, EARMUTE | Active-high mute controls | Provide 80 dB attenuation of TX/RX paths independently-critical for call setup, DTMF, and sidetone management. |
| LINSEL | Mode selection input | Low = 13-bit linear mode; high = 8-bit µ-law companding-configurable per system protocol requirements. |
| RESET | Active-low asynchronous reset | Requires ≥500 ns pulse with MCLK active to ensure deterministic power-up initialization and state recovery. |
| DVDD/DVSS, EARVDD/EARVSS, VSS | Separate power/ground domains | Isolates digital, analog earphone, and bandgap reference supplies to minimize noise coupling between domains. |
Key Features
| Feature | Design Value |
|---|---|
| Differential microphone interface with external gain setting | Enables >23 dB SNR with 1% resistor tolerance; supports flexible mic biasing and noise immunity in noisy handset environments. |
| Programmable earphone volume in linear mode | Three-bit RXVOL control (−18 dB to +3 dB) embedded in PCM data stream-eliminates need for external DAC or I²C interface. |
| CCITT G.714–compliant digital filters | Guarantees passband flatness (±0.5 dB from 300 Hz–3 kHz) and stopband rejection (−35 dB at 4.6 kHz), meeting telecom certification requirements. |
| 2.048 MHz master clock operation | Direct compatibility with E1 line timing; eliminates need for external clock dividers or jitter-cleaning circuits in infrastructure equipment. |
| Power-down mode with 30 µA quiescent current | Enables rapid wake-up (<10 ms) while preserving battery life in portable voice recorders and cordless handsets during idle periods. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PCM codec applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV320AIC101IDBT | Single-supply (2.7–3.6 V), 16-pin QFN, no µ-law mode, 12-bit linear only, lower output drive (100 mW @ 16 Ω) | Targeted at cost-sensitive consumer headsets; lacks PSTN-grade filtering and companding required for PABX/cordless base stations | Select when µ-law compatibility and G.714 compliance are unnecessary and board space is constrained. |
| CS42L52-CNZ | Low-power stereo codec (1.65–3.6 V), I²S/PCM interface, integrated LDOs, −95 dB THD+N, but no µ-law support | Designed for smartphones/tablets with stereo audio; lacks dedicated mic preamp gain control and telecom-specific mute timing | Prefer for portable multimedia devices needing stereo playback/recording-not suitable for voice-band-only telecom endpoints. |
Compared with TLV320AIC1106PWG4, TLV320AIC101IDBT offers smaller footprint but sacrifices µ-law support and telecom filter compliance, while CS42L52-CNZ adds stereo capability and lower noise at the expense of missing critical telephony features like LINSEL-controlled companding and G.714-certified filtering.

FAQ
What is the primary function of the TLV320AIC1106PWG4 in a voice communication system?
The TLV320AIC1106PWG4 serves as a complete PCM audio codec IC, performing analog-to-digital conversion of microphone signals and digital-to-analog conversion for earphone output, while integrating transmit/receive digital filters compliant with CCITT G.714. It enables full-duplex voice communication in digital handsets, cordless phones, and PABX terminals without requiring external converters or filters.
Does the TLV320AIC1106PWG4 support both µ-law and linear PCM modes, and how is mode selection implemented?
Yes, the TLV320AIC1106PWG4 supports both 8-bit µ-law and 13-bit linear PCM modes. Mode selection is controlled by the LINSEL input: logic low selects linear mode (13-bit words, RXVOL bits enable volume control), and logic high selects µ-law mode (8-bit words, fixed 0 dB volume). This dual-mode capability allows seamless integration into both legacy µ-law PSTN systems and modern linear-data infrastructure.
What are the power supply requirements and consumption characteristics of the TLV320AIC1106PWG4?
The TLV320AIC1106PWG4 operates from a single 2.7 V to 3.3 V supply for DVDD and EARVDD, with separate DVSS, EARVSS, and VSS grounds. Typical active supply current is 7 mA; power-down current drops to 30 µA when MCLK is absent. Power-up time from power-down is ≤10 ms, and the device enters automatic power-down if MCLK stops, placing PCMO in high-impedance state.
How does the TLV320AIC1106PWG4 handle microphone input and earphone output interfaces?
The TLV320AIC1106PWG4 features a differential microphone input (MICIN+/MICIN−) with externally configurable gain via MICGAIN+/MICGAIN− pins, supporting up to 23.5 dB with 1% resistors. Its earphone output (EAROUT+/EAROUT−) is fully differential, capable of driving 8–32 Ω loads with up to 200 mW output power and built-in click/pop suppression-no external components required for basic operation.
What packaging and environmental specifications apply to the TLV320AIC1106PWG4?
The TLV320AIC1106PWG4 is housed in a 20-pin TSSOP (PW) package measuring 4.4 mm × 6.5 mm with 0.65 mm lead pitch. It carries RoHS-compliant NIPDAU lead finish, MSL Level-1 rating (unlimited floor life at <30°C/60% RH), and operates across −40°C to +85°C. The part marking is "AIC1106", and it ships in tubes of 70 units.
