TLV320AIC15IDBTR

Codecs Overview

The TLV320AIC15IDBTR is a low-power, highly integrated mono audio codec manufactured by Texas Instruments. It features one 16-bit analog-to-digital converter and one 16-bit digital-to-analog converter utilizing oversampling sigma-delta technology. The device supports a maximum sampling rate of 26 kSPS with on-chip filters or up to 104 kSPS when filters are bypassed. It operates with a digital core voltage range of 1.65 V to 1.95 V, a digital I/O range of 1.1 V to 3.6 V, and an analog supply range of 2.7 V to 3.6 V. The component provides typical signal-to-noise ratios of 84 dB for the ADC and 92 dB for the DAC. It is housed in a 30-pin TSSOP package and is characterized for industrial operation from -40°C to +85°C.

Codecs Procurement Notes

Verify the specific ordering suffix IDBTR confirms the industrial temperature range (-40°C to +85°C) and the tape-and-reel packaging format. Confirm that the component matches the standard production data specifications provided in the datasheet SLWS115E. Ensure compatibility with the required analog and digital supply voltages before finalizing procurement orders.

Codecs Selection Notes

Select this component for voice-band applications requiring low power consumption and high integration. It is suitable for designs needing a mono codec with built-in filters and programmable gain. Consider the 30-pin TSSOP package constraints and the requirement for separate analog and digital power supplies when designing the system architecture.

Codecs Part Context

This part belongs to the TLV320AIC1x family of low-power audio codecs. It shares functional similarities with the TLV320AIC12, AIC13, and AIC14 models but differs in specific pin configurations and output driver capabilities. The 'I' designation indicates the industrial temperature grade, while 'DBTR' specifies the surface-mount TSSOP-30 package in a tape-and-reel configuration.

Codecs Replacement Considerations

The TLV320AIC14KIDBTR is a compatible alternative within the same family offering similar mono codec functionality. Verify pinout compatibility and ensure the replacement meets the specific industrial temperature and voltage requirements of the original design.
