AK5380VT Equivalent & Substitute Parts

Part Overview

The AK5380VT is a 24-bit audio ADC with 96 kHz sampling rate and I2S digital interface, manufactured by Asahi Kasei Microdevices (AKM). This component is classified as obsolete, making substitute parts necessary for new designs and ongoing production requirements. The part operates across a wide supply voltage range of 2.7V to 5.5V and is housed in a 16-TSSOP surface mount package. Identifying compatible alternatives ensures design continuity and component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AK5380VT are evaluated based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Audio ADC functionality with 2-channel configuration
• I2S digital interface compatibility
• Surface mount packaging
• Operating temperature range support
• Supply voltage compatibility

Substitute Classification:

Direct Form Factor Substitute (Recommended for Pin-Compatible Replacement): The AK5720VT maintains identical package type (16-TSSOP), channel count (2), resolution (24 bits), sampling rate (96 kHz), and I2S interface. This part is active in production status and supports the same supply voltage range (2.7V ~ 5.5V), making it the primary direct replacement for the obsolete AK5380VT.

Enhanced Performance Substitutes (Functional Alternatives): The AK5522VN and AK5552VN offer increased resolution and sampling rates but require different package footprints and may require design modifications. These parts are suitable when higher performance specifications are acceptable within the application requirements.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Recommended): The AK5720VT is the primary substitute for the AK5380VT. Both parts share identical electrical specifications (24-bit resolution, 96 kHz sampling rate, I2S interface, 2.7V ~ 5.5V supply voltage) and package footprint (16-TSSOP). The AK5720VT is active in production status and ROHS3 compliant, providing long-term availability and regulatory compliance. The extended operating temperature range (-40°C ~ 105°C versus -40°C ~ 85°C) offers improved thermal performance margins.

For Enhanced Performance Applications: The AK5522VN provides 32-bit resolution and 192 kHz sampling rate with I2S interface, suitable for applications requiring higher audio fidelity. This part requires a different package footprint (24-HQFN) and modified PCB layout. Supply voltage requirements differ, with separate analog (4.5V ~ 5.5V) and digital (3.3V ~ 5V) supplies.

The AK5552VN offers the highest performance with 32-bit resolution and 768 kHz sampling rate, supporting both DSD and PCM interfaces. This part requires the largest package footprint (48-QFN) and supports multiple supply voltage configurations. Selection of this part is appropriate only when the application specifically requires high-resolution audio processing capabilities.

Compliance Considerations: All active substitute parts (AK5720VT, AK5522VN, AK5552VN) are ROHS3 compliant, meeting current environmental regulations. The AK5720VT maintains MSL 1 rating identical to the original part, while AK5522VN and AK5552VN carry MSL 2 ratings requiring controlled storage conditions.

Frequently Asked Questions (FAQ)

Q: Can the AK5720VT be used as a direct replacement for the AK5380VT without PCB modifications?

A: Yes. The AK5720VT is pin-compatible and uses the identical 16-TSSOP package footprint. Both parts share the same electrical interface specifications (24-bit resolution, 96 kHz sampling rate, I2S protocol, 2.7V ~ 5.5V supply voltage). No PCB layout changes are required for this substitution.

Q: What are the key differences between the AK5720VT and AK5522VN?

A: The AK5720VT maintains 24-bit resolution and 96 kHz sampling rate in a 16-TSSOP package. The AK5522VN increases resolution to 32 bits and sampling rate to 192 kHz, but requires a larger 24-HQFN package footprint. The AK5522VN also requires separate analog and digital supply voltages, whereas the AK5720VT accepts a single supply voltage range.

Q: Is the AK5552VN suitable for all applications requiring the AK5380VT?

A: The AK5552VN is functionally compatible but introduces significant design changes. It requires a 48-QFN package (substantially larger than the 16-TSSOP), supports DSD and PCM interfaces (versus I2S only), and operates at 768 kHz sampling rate. Selection of this part is appropriate only when the application specifically requires these enhanced capabilities.

Q: What is the impact of MSL rating differences between substitute parts?

A: The AK5380VT and AK5522VN carry MSL 1 ratings, allowing unlimited shelf life under standard conditions. The AK5720VT and AK5552VN carry MSL 2 ratings, requiring controlled storage with a 1-year floor life limit. MSL 2 components require moisture-controlled packaging and handling procedures during storage and assembly.

Q: Are all substitute parts ROHS3 compliant?

A: All active substitute parts (AK5720VT, AK5522VN, AK5552VN) are ROHS3 compliant. The original AK5380VT compliance status is not specified in available documentation.

Q: What supply voltage considerations apply when selecting a substitute?

A: The AK5720VT accepts the same 2.7V ~ 5.5V supply voltage as the AK5380VT. The AK5522VN requires separate analog (4.5V ~ 5.5V) and digital (3.3V ~ 5V) supplies. The AK5552VN supports multiple voltage configurations (1.7V ~ 1.98V, 3V ~ 3.6V, 5V), providing flexibility for low-power applications.
