TAA3040IRTWR

ADCs/DACs - Special Purpose Overview

The TAA3040IRTWR is a quad-channel audio analog-to-digital converter (ADC) from Texas Instruments, housed in a 24-pin WQFN package. It supports simultaneous sampling of four analog channels or eight digital PDM microphone inputs at sample rates up to 768 kHz. Key electrical specifications include a dynamic range of 104 dB and THD+N of -95 dB for differential line/microphone inputs. The device operates on a single AVDD supply of 1.8 V or 3.3 V and IOVDD of 1.8 V or 3.3 V. It features programmable channel gain, digital volume control, and integrated PLL for clock generation.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix 'IRTWR' corresponds to the 24-pin WQFN package and tape-and-reel packaging format as defined in the manufacturer's datasheet. Confirm that the component meets RoHS compliance requirements for the intended market. Ensure the procurement source provides valid traceability documentation consistent with Texas Instruments production data standards.

ADCs/DACs - Special Purpose Selection Notes

Select this component when designing space-constrained audio systems requiring far-field microphone recording capabilities. The TAA3040IRTWR is suitable for applications needing high channel count integration with low-latency signal processing. Consider the 1.8 V or 3.3 V single-supply operation and the availability of an evaluation module (TAA3040EVM-PDK) for development validation.

ADCs/DACs - Special Purpose Part Context

The TAA3040 belongs to the Burr-Brown family of high-performance audio ADCs. It is designed to replace discrete solutions by integrating front-end PGA, digital filters, and clock generation into a single chip. The device is specified for industrial temperature ranges from -40°C to +105°C, ensuring reliability in various environmental conditions.

ADCs/DACs - Special Purpose Replacement Considerations

The TAA3040EVM-PDK is the official evaluation module for this device. No direct cross-model substitutes are listed in the provided documentation; verify compatibility with existing system architectures before considering alternative part numbers.
