PCM2707PJTG4 Equivalent & Substitute Parts

Part Overview

The PCM2707PJTG4 is a 16-bit stereo audio codec with integrated USB and SPI interfaces, designed for audio data acquisition applications. Manufactured by Texas Instruments, this component operates across dual voltage supplies (3V–3.6V and 5V) with a 48 kHz sampling rate and 32-TQFP surface mount packaging.

The PCM2707PJTG4 is classified as obsolete. Identifying equivalent and substitute parts is essential for ongoing system support, design updates, and procurement continuity when original inventory becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PCM2707PJTG4 is determined by the following critical parameters:

• Audio Codec Functionality: 16-bit resolution, 2-channel stereo configuration, 48 kHz sampling rate
• Interface Compatibility: SPI and USB data interfaces
• Voltage Supply Requirements: Dual supply operation (3V–3.6V and 5V)
• Thermal Operating Range: Minimum -40°C to 125°C
• Surface Mount Packaging: TQFP or equivalent surface mount package

The PCM2705CDB meets these core functional requirements. While it operates within a narrower temperature range (-25°C to 85°C) and uses a different package footprint (28-SSOP versus 32-TQFP), it maintains identical audio specifications, interface protocols, and voltage supply compatibility. Package differences require PCB layout redesign but do not affect electrical substitution viability.

Parameter Comparison

Engineering Selection Recommendations

The PCM2705CDB is the designated manufacturer-recommended substitute for the PCM2707PJTG4. Both components maintain identical audio codec specifications and interface protocols, ensuring functional compatibility at the circuit level.

Product Status Consideration: The PCM2707PJTG4 is obsolete, while the PCM2705CDB is active. Active product status ensures ongoing availability, manufacturing support, and compliance documentation.

Compliance and Certifications: The PCM2707PJTG4 carries ROHS3 compliance and REACH unaffected status. The PCM2705CDB's compliance certifications are not specified in the provided data. Verification of regulatory compliance requirements for your application is necessary before final selection.

Temperature Range Limitation: The PCM2705CDB operates within -25°C to 85°C, which is narrower than the PCM2707PJTG4's -40°C to 125°C range. Applications requiring extended temperature operation below -25°C or above 85°C must account for this constraint.

Package Footprint Change: The transition from 32-TQFP to 28-SSOP requires PCB redesign. Pin-to-pin functional mapping must be verified against device datasheets to ensure correct signal routing.

Frequently Asked Questions (FAQ)

Q: Can the PCM2705CDB directly replace the PCM2707PJTG4 without PCB modifications?

A: Electrical substitution is viable; however, package differences (32-TQFP versus 28-SSOP) require PCB layout redesign. Pin assignments and signal routing must be verified against both device datasheets before implementation.

Q: What is the impact of the narrower operating temperature range on the PCM2705CDB?

A: The PCM2705CDB operates from -25°C to 85°C, compared to the PCM2707PJTG4's -40°C to 125°C range. Applications operating outside the -25°C to 85°C window must use the original part or identify alternative solutions.

Q: Are the audio specifications identical between these two parts?

A: Yes. Both components provide 16-bit resolution, 2-channel stereo configuration, and 48 kHz sampling rate with SPI and USB interface support.

Q: What voltage supplies are required for the PCM2705CDB?

A: The PCM2705CDB requires dual supplies: 3V–3.6V and 5V, identical to the PCM2707PJTG4.

Q: Is the PCM2705CDB RoHS compliant?

A: RoHS compliance status for the PCM2705CDB is not specified in the provided technical data. Consult the manufacturer's documentation or supplier for current compliance certifications.

Q: Why is the PCM2707PJTG4 classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by Texas Instruments. The PCM2705CDB, maintained as an active product by Burr Brown, provides continuity for audio codec applications.
