TLV320AIC1110GQER

Codecs Overview

The TLV320AIC1110GQER is a mono PCM audio codec manufactured by Texas Instruments, designed for low-power voice band applications. It operates on a supply voltage range of 2.7 V to 3.3 V and supports industrial temperatures from -40°C to +85°C. The device features two differential microphone inputs and provides both differential (EAR1) and single-ended (EAR2) earphone outputs. It utilizes a standard two-wire I2C serial interface for register control. The codec supports 15-bit linear data or 8-bit companded modes (µ-law/A-law) and accommodates PCM clock rates of 128 kHz and 2.048 MHz.

Codecs Feature Summary

• Integrated DTMF and single-tone generator with selectable frequency resolutions
• On-chip phase-locked loop (PLL) for internal clock generation
• Configurable transmit and receive paths with programmable gain and attenuation
• Built-in analog multiplexer for auxiliary signal routing

Codecs Applications

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

Codecs Procurement Notes

Verify the GQE suffix indicates the MicroStar Junior BGA package variant rather than the TQFP option. Confirm that the specific revision matches the SLAS359 datasheet requirements. Ensure the component meets the specified industrial temperature range and voltage limits for your target application environment before finalizing orders.

Codecs Selection Notes

Select this model when a compact BGA footprint is required compared to the pin-compatible TQFP versions. Consider the integrated tone generator and analog switch if system-level discrete components need reduction. Verify power consumption constraints against the typical operating current specifications provided in the electrical characteristics table.

Codecs Part Context

This component belongs to the TLV320AIC1110 series of PCM codecs. It shares functional similarities with the TLV320AIC1103 and TLV320AIC1109 but differs primarily in its physical packaging options. The GQER designation specifically identifies the MicroStar Junior BGA package configuration within the broader product family.

Codecs Replacement Considerations

The TLV320AIC1103 and TLV320AIC1109 are documented as pin-compatible alternatives for the TQFP package only. Direct substitution into the MicroStar Junior BGA footprint requires verifying mechanical compatibility and checking for any specific feature differences between these sibling models.
