DIR9001PWR

Audio Special Purpose Overview

The DIR9001PWR is a digital audio receiver manufactured by Texas Instruments, designed for high-fidelity audio signal processing. It features a single channel with 24-bit resolution and supports sampling rates from 28kHz to 108kHz. The device operates on a supply voltage range of 2.7V to 3.6V and consumes power within an operating temperature range of -40°C to +85°C. It utilizes an I2S serial interface for data transmission and is housed in a 28-TSSOP package. This component is suitable for applications requiring precise digital audio reception in consumer electronics and musical instruments.

Audio Special Purpose Feature Summary

• Single-channel digital audio receiver with 24-bit resolution
• Supports sampling frequencies between 28kHz and 108kHz
• Operates on a 2.7V to 3.6V supply voltage
• I2S serial interface for digital audio data input

Audio Special Purpose Applications

• Audio equipment systems
• Musical instrument interfaces
• Digital audio processing units

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix 'PWR' corresponds to the Tape & Reel packaging configuration when sourcing components. Confirm that the automotive grade designation aligns with project requirements, as standard variants may differ in qualification status. Ensure compatibility with the 28-TSSOP footprint during PCB layout verification.

Audio Special Purpose Selection Notes

Select this component for designs requiring a single-channel I2S receiver with support for sample rates up to 108kHz. The 2.7V to 3.6V supply range fits low-voltage digital logic systems. Consider the 28-TSSOP package dimensions (4.40mm width) for space-constrained surface-mount applications. Verify thermal performance within the -40°C to +85°C operational envelope.

Audio Special Purpose Part Context

The DIR9001PWR belongs to the DIR9001 series of digital audio receivers from Texas Instruments. It serves as a specialized integrated circuit for converting serial digital audio streams into parallel data formats. The 'PWR' suffix indicates the tape-and-reel packaging variant, distinct from tube-packaged versions like the DIR9001PW.

Audio Special Purpose Replacement Considerations

Check for direct pin-compatible substitutes within the same family, such as the DIR9001PW, noting differences in packaging. Evaluate other single-channel I2S receivers if automotive qualification is not strictly required.
