TLV320AIC1110PBSR

Codecs Overview

The TLV320AIC1110PBSR is a low-power PCM codec manufactured by Texas Instruments, designed for analog and digital wireless handsets. It operates on a single supply voltage ranging from 2.7 V to 3.3 V across an industrial temperature range of -40°C to +85°C. The device features two differential microphone inputs and supports both 15-bit linear and 8-bit companded (µ-law/A-law) data formats. It includes a programmable I²C interface, DTMF tone generation, and earphone amplifiers capable of driving loads as low as 8 Ω differentially or 32 Ω single-ended.

Codecs Feature Summary

• Supports dual differential microphone inputs with selectable gain stages
• Provides differential and single-ended earphone outputs with integrated amplification
• Includes programmable transmit, receive, and sidetone paths with extended gain ranges
• Features an on-chip I²C bus for simple control of registers and power modes

Codecs Applications

• Digital handsets
• Digital headsets
• Cordless phones
• Digital PABX systems
• Digital voice recording devices

Codecs Procurement Notes

Verify the specific package variant when ordering, as the PBSR suffix indicates a TQFP-32 package in a reel. Confirm that the application circuit provides the required external precision resistor at the REXT terminal for reference current setting. Ensure the host controller supports the standard two-wire I²C serial interface for register configuration and power management.

Codecs Selection Notes

Select this component for applications requiring a mono audio codec with high drive capability for speakerphones due to its ability to drive 8 Ω loads. Consider the available 15-bit linear resolution for higher fidelity requirements or 8-bit companding for bandwidth efficiency. Verify compatibility with the system's master clock frequencies of 128 kHz or 2.048 MHz for proper PCM interface synchronization.

Codecs Part Context

This device belongs to the TLV320AIC11xx series of PCM codecs from Texas Instruments. It is pin-compatible with the TLV320AIC1103 and TLV320AIC1109 devices in the TQFP package, facilitating design upgrades or replacements within existing hardware layouts without requiring PCB redesigns.

Codecs Replacement Considerations

The TLV320AIC1103 and TLV320AIC1109 are confirmed pin-compatible substitutes for the TQFP package variant.
