TS482IST Equivalent & Substitute Parts

Part Overview

The TS482IST is a Class AB stereo headphone amplifier integrated circuit manufactured by STMicroelectronics. This surface-mount device delivers 107mW per channel at 16Ω load across a 2V to 5.5V supply range, with integrated depop functionality for audio applications. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance, supply voltage compatibility, and thermal operating range align with application requirements while maintaining the same functional output classification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TS482IST are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Output Type: Headphones, 2-Channel (Stereo) Class AB amplification
• Voltage Supply Range: 2V ~ 5.5V compatibility
• Operating Temperature Range: -40°C ~ 85°C (TA)
• Mounting Type: Surface Mount
• Package Classification: 8-pin TSSOP/MSOP footprint family
• Features: Depop functionality
• Compliance: RoHS3 Compliant, MSL 1 rating

Allowable Variation:

• Maximum Output Power: Substitute parts may exceed the 107mW specification per channel at 16Ω load, as higher output capability does not restrict application in circuits designed for lower power delivery
• Packaging Designation: Variations within the 8-pin TSSOP/MSOP family (8-VSSOP) are acceptable due to compatible footprint and pin configuration

The LM4808MM/NOPB and LM4808MMX/NOPB from Texas Instruments meet all critical parameters with enhanced output power specification of 150mW per channel at 16Ω load.

Parameter Comparison

Engineering Selection Recommendations

TS482IST (Primary Part): The TS482IST remains the primary selection for applications requiring the specified 107mW output power per channel. This part maintains Active product status with full RoHS3 compliance and MSL 1 rating, ensuring long-term availability and regulatory compliance for consumer and industrial audio applications.

LM4808MM/NOPB and LM4808MMX/NOPB (Substitute Parts): Both Texas Instruments LM4808 variants qualify as direct substitutes based on matching electrical specifications, supply voltage range, operating temperature range, and compliance certifications. The increased output power specification of 150mW per channel at 16Ω load provides additional headroom for audio applications without compromising compatibility. Both parts maintain Active product status with identical RoHS3 and MSL 1 compliance. Selection between LM4808MM/NOPB and LM4808MMX/NOPB depends on inventory availability and packaging requirements, as both parts share identical electrical and thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can the LM4808MM/NOPB directly replace the TS482IST in existing designs?

A: Yes. Both parts share identical supply voltage range (2V ~ 5.5V), operating temperature range (-40°C ~ 85°C), Class AB stereo output configuration, depop functionality, and 8-pin TSSOP/MSOP package footprint. The LM4808MM/NOPB delivers 150mW per channel at 16Ω, exceeding the TS482IST specification of 107mW per channel, which does not restrict application compatibility.

Q: What is the difference between LM4808MM/NOPB and LM4808MMX/NOPB?

A: Both parts are functionally identical with matching electrical specifications, supply voltage, operating temperature, and compliance ratings. The difference lies in packaging designation and inventory availability. Selection should be based on supply chain requirements and part availability.

Q: Are there package compatibility concerns when substituting these parts?

A: No. All three parts (TS482IST, LM4808MM/NOPB, and LM4808MMX/NOPB) utilize the 8-pin TSSOP/MSOP package family with 0.118" width and 3.00mm pitch, ensuring PCB footprint compatibility without layout modifications.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. The TS482IST and both LM4808 variants are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, REACH Unaffected status, and EAR99 export classification. All parts maintain Active product status.

Q: What determines whether a part qualifies as a substitute?

A: Substitution is based on matching output type (Headphones, 2-Channel Stereo Class AB), supply voltage range (2V ~ 5.5V), operating temperature range (-40°C ~ 85°C), mounting type (Surface Mount), package family (8-pin TSSOP/MSOP), integrated features (Depop), and compliance certifications (RoHS3, MSL 1). Output power specifications may exceed the primary part without restricting substitution eligibility.
