TS482ID Equivalent & Substitute Parts

Part Overview

The TS482ID is a Class AB stereo amplifier IC manufactured by STMicroelectronics, designed for headphone applications with 2-channel output capability. This device delivers 107mW per channel at 16Ohm load impedance and operates across a 2V to 5.5V supply voltage range. The TS482ID is classified as obsolete, necessitating identification of equivalent substitute components for ongoing design requirements and production continuity. Active alternative parts with compatible electrical and mechanical specifications are available from other manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TS482ID are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Compatibility Criteria:

• Amplifier topology: Class AB
• Output configuration: Headphones, 2-Channel (Stereo)
• Supply voltage range: 2V ~ 5.5V (identical or encompassing range)
• Operating temperature range: -40°C ~ 85°C (TA)
• Depop feature presence

Mechanical Compatibility Criteria:

• Package type: 8-SOIC
• Package dimensions: 0.154" width, 3.90mm width
• Mounting type: Surface Mount

Regulatory & Compliance Criteria:

• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts identified (LM4808M/NOPB and LM4808MX/NOPB) satisfy all mandatory electrical and mechanical parameters. Output power specifications exceed the TS482ID baseline, providing enhanced performance capability within the same package footprint and supply voltage constraints.

Parameter Comparison

Engineering Selection Recommendations

LM4808M/NOPB (Texas Instruments) is the primary substitute for the TS482ID. This part maintains full electrical and mechanical compatibility while offering increased output power capability (150mW per channel versus 107mW). The device carries Active product status with confirmed ROHS3 compliance, ensuring long-term availability and regulatory alignment. Packaging is identical (8-SOIC), enabling direct PCB layout compatibility without redesign.

LM4808MX/NOPB (National Semiconductor) serves as a secondary substitute option. This variant provides equivalent electrical performance (150mW per channel output) and identical mechanical specifications (8-SOIC package). The device maintains Active product status. Compliance documentation for RoHS and moisture sensitivity is not specified in available data; verification of regulatory requirements against design specifications is necessary prior to selection.

Both substitute parts operate within the identical supply voltage range (2V ~ 5.5V) and temperature envelope (-40°C ~ 85°C), ensuring functional interchangeability in existing circuit designs. The enhanced output power of both substitutes provides performance margin above the original TS482ID specification.

Frequently Asked Questions (FAQ)

Q: Can the LM4808M/NOPB directly replace the TS482ID without PCB modifications?

A: Yes. Both devices utilize the 8-SOIC package with identical dimensions (0.154" x 3.90mm width). Pin configuration and electrical interface specifications are compatible, permitting direct substitution on existing PCB layouts without redesign.

Q: What is the primary difference between the TS482ID and its substitutes?

A: The TS482ID delivers 107mW per channel output power, while both LM4808M/NOPB and LM4808MX/NOPB deliver 150mW per channel. All three devices operate across the same 2V to 5.5V supply voltage range and share identical Class AB topology, temperature range, and package specifications.

Q: Why is the TS482ID classified as obsolete?

A: The TS482ID is marked as obsolete by STMicroelectronics. Active equivalent parts from Texas Instruments and National Semiconductor provide continued design support and production availability.

Q: Are there any supply voltage or temperature limitations when substituting?

A: No. The substitute parts maintain the identical supply voltage range (2V ~ 5.5V) and operating temperature range (-40°C ~ 85°C TA) as the original TS482ID. No circuit modifications are required for these parameters.

Q: What is the Depop feature and is it present in all substitute parts?

A: Depop is a de-popping circuit feature that eliminates audible clicks and pops during power-on and power-off transitions in audio amplifiers. All three parts (TS482ID, LM4808M/NOPB, and LM4808MX/NOPB) include this feature.

Q: Which substitute part should be selected for new designs?

A: The LM4808M/NOPB is recommended for new designs due to its Active product status, confirmed ROHS3 compliance, and availability from Texas Instruments. This ensures long-term supply continuity and regulatory compliance documentation.

Q: Is the LM4808MX/NOPB suitable for production use?

A: The LM4808MX/NOPB is electrically and mechanically compatible with the TS482ID and carries Active product status. However, complete compliance documentation (RoHS, moisture sensitivity) should be verified against specific design and regulatory requirements before production implementation.

Q: What is the moisture sensitivity level (MSL) and why does it matter?

A: MSL indicates the maximum time a component can be exposed to ambient conditions before soldering. MSL 1 (Unlimited) means the part has no moisture absorption restrictions and can be stored indefinitely without special drying procedures prior to assembly.
