TLV320ADC3140IRTWR

ADCs/DACs - Special Purpose Overview

The TLV320ADC3140IRTWR is a quad-channel audio analog-to-digital converter (ADC) from Texas Instruments, part of the Burr-Brown series. It features a sampling rate up to 768 kHz and operates within an analog supply voltage range of 1.7 V to 3.6 V. The device provides high-fidelity performance with a signal-to-noise ratio (SNR) of 106 dB and total harmonic distortion plus noise (THD+N) of -98 dB. Packaged in a WQFN-24 form factor for surface mount installation, it supports operation temperatures from -40°C to +125°C.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix 'IRTWR' corresponds to the WQFN-24 package and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design specifications align with the 1.7 V to 3.6 V analog supply voltage limits and the -40°C to +125°C operational temperature range defined in the datasheet.

ADCs/DACs - Special Purpose Selection Notes

Select this component when four independent ADC channels are required for spatial audio processing or microphone array applications. Compare against stereo alternatives like the TLV320ADC5120 if channel count is insufficient, or evaluate lower-power options if power consumption is critical. Verify interface compatibility and ensure the WQFN-24 footprint fits the PCB layout constraints.

ADCs/DACs - Special Purpose Part Context

This part belongs to the TLV320ADC3140 family of high-performance audio ADCs. It is distinct from stereo variants such as the TLV320ADC5120 and legacy CODECs like the TLV320AIC31 series. The 'IRTWR' designation indicates the industrial temperature grade, WQFN-24 package, and tape-and-reel shipping format.

ADCs/DACs - Special Purpose Replacement Considerations

Direct pin-compatible substitutes within the same family include other TLV320ADC31xx variants with matching channel counts. For system upgrades, consider the TLV320ADC5140 for higher resolution requirements, though package and pinout differences must be evaluated.
