TLV320AIC12IDBTG4

Codecs Overview

The TLV320AIC12IDBTG4 is a low-power, highly integrated mono voice band audio codec manufactured by Texas Instruments. It features one 16-bit oversampling sigma-delta analog-to-digital converter (ADC) and one 16-bit digital-to-analog converter (DAC). The device supports a maximum sampling rate of 26 kSPS with on-chip IIR/FIR filters or up to 104 kSPS when the filters are bypassed. It operates with a digital core supply voltage range of 1.65 V to 1.95 V and an analog supply voltage range of 2.7 V to 3.6 V. The component is housed in a 30-pin TSSOP package and is characterized for industrial operation from -40°C to +85°C.

Codecs Feature Summary

• Integrates programmable gain amplifiers, microphone preamplifiers, handset amplifiers, and headset amplifiers for comprehensive voice signal conditioning.
• Supports Smart Time Division Multiplexed (SMARTDM) serial interface for glueless connection to DSPs and microcontrollers, allowing cascading of up to 16 devices.
• Includes selectable FIR/IIR digital filters and an antialiasing filter to optimize voice band signal processing.
• Provides extensive power management capabilities with independent software control for ADC, DAC, and operational amplifiers to minimize system power consumption.

Codecs Applications

• Wireless accessories
• Hands-free car kits
• Voice over IP (VOIP) systems
• Cable modems
• Speech processing applications

Codecs Procurement Notes

Verify the specific ordering suffix IDBTG4 against the manufacturer's current datasheet to confirm package type, temperature range, and RoHS compliance status. Ensure that the required supply voltages match the specified ranges for the digital core and analog sections before integration into the design.

Codecs Selection Notes

Select this component for mono voice-band applications requiring low power consumption and high integration. Consider the available digital filters and programmable gain stages if signal conditioning is needed. Verify compatibility with the host processor's serial interface protocol, such as SMARTDM or standard I2C/S2C for register configuration.

Codecs Part Context

This part belongs to the TLV320AIC1x family of low-power audio codecs from Texas Instruments. The family includes variants like the TLV320AIC12, TLV320AIC13, TLV320AIC14, and TLV320AIC15, which share similar functional blocks but may differ in output driver capabilities or package options. The 'I' designation indicates industrial temperature range operation.

Codecs Replacement Considerations

Direct replacements within the same family include the TLV320AIC12IDBT and TLV320AIC13IDBT. Verify pinout compatibility and electrical specifications, particularly regarding output drive strength and power supply requirements, when substituting these parts.
