TAC5142IRGER

Codecs Overview

The TAC5142IRGER is a stereo audio codec manufactured by Texas Instruments, housed in a 24-pin VQFN package. It features a 103dB dynamic range ADC and a 110dB dynamic range DAC. The device supports sample rates from 8kHz to 192kHz with selectable word lengths of 24 or 32 bits. It operates on a single analog supply (AVDD) of 1.65V to 3.6V and an I/O supply (IOVDD) of 1.65V to 3.6V. The component functions within an ambient temperature range of -40°C to +125°C.

Codecs Feature Summary

• Hardware-controlled configuration via pin-selectable modes for controller and target operations without digital interface programming.
• Integrated phase-locked loop (PLL) supporting auto clock and sample rate detection for simplified system synchronization.
• Configurable digital high-pass filter with selectable cutoff frequencies to manage DC offsets in the ADC signal chain.

Codecs Applications

• Video Conference Systems
• IP Network Cameras
• IP Telephones
• Smart Speakers
• Professional Audio Mixers

Codecs Procurement Notes

Verify the specific ordering suffix against the manufacturer's current orderable addendum to ensure correct packaging and tape-and-reel specifications. Confirm that the voltage ratings match the target application's power supply rails before finalizing procurement orders.

Codecs Selection Notes

Select this component when hardware control is preferred over software-based register configuration to reduce processor overhead. Ensure the design accommodates the required differential input/output voltage levels and verify compatibility with the host system's serial audio interface timing requirements.

Codecs Part Context

This device belongs to the TAC51xx series of stereo audio codecs designed for space-constrained applications. It shares pin-to-pin and package compatibility with other members of the family, allowing for drop-in replacements depending on specific performance requirements such as channel count or dynamic range needs.

Codecs Replacement Considerations

The TAC5142 is pin-compatible with the TAC5112, TAC5212, TAC5242, TAC5111, and TAC5211. These devices serve as direct drop-in replacements within the same package footprint while maintaining control register compatibility.
