TLV320AIC14KIDBTG4

Codecs Overview

The TLV320AIC14KIDBTG4 is a low-power, highly integrated mono voice codec manufactured by Texas Instruments. It features one 16-bit oversampling sigma-delta analog-to-digital converter and one 16-bit digital-to-analog converter. The device supports a maximum sampling rate of 26 kSPS with on-chip IIR/FIR filters or up to 104 kSPS when filters are bypassed. It operates with a digital core supply voltage ranging from 1.65 V to 1.95 V, a digital I/O supply from 1.1 V to 3.6 V, and an analog supply from 2.7 V to 3.6 V. The component is housed in a 30-pin TSSOP package and is characterized for industrial operation between -40°C and +85°C.

Codecs Feature Summary

• Integrates programmable gain amplifiers, microphone preamplifiers, handset amplifiers, headset amplifiers, and selectable FIR/IIR filters for comprehensive voice-band signal processing.
• Supports glueless interface to DSPs via SMARTDM serial port and flexible host port compatible with I2C or S2C protocols.
• Enables automatic cascade detection allowing up to 16 devices to share a single serial port for multichannel expansion.

Codecs Applications

• Wireless accessories
• Hands-free car kits
• VOIP systems
• Speech processing

Codecs Procurement Notes

Verify the suffix 'G4' indicates lead-free compliance and RoHS conformity as per manufacturer standards. Confirm the 'I' designator specifies the industrial temperature range of -40°C to +85°C. Ensure the 'DBTR' transport media matches the required tape and reel quantity for production integration. Cross-reference the specific ordering number against current Texas Instruments documentation to validate availability status.

Codecs Selection Notes

Select this component for applications requiring a mono voice codec with integrated power management and low group delay. The device is suitable for single or multichannel active control scenarios due to its timing characteristics. Consider the available output drivers and input configurations when designing the analog front end. Verify that the system clock requirements align with the maximum master clock support of 100 MHz.

Codecs Part Context

This part belongs to the TLV320AIC1x family of low-cost, low-power audio codecs. The 'K' variant specifically denotes industrial temperature rating (-40°C to +85°C), distinguishing it from commercial grade parts. The 'G4' suffix typically signifies lead-free packaging and environmental compliance within the Texas Instruments product line.

Codecs Replacement Considerations

TLV320AIC14KIDBT is the non-lead-free equivalent. TLV320AIC12KIDBTR shares similar architecture but includes an 8-ohm speaker driver not present in the AIC14K.
