Equivalent & Substitute Parts for LM4892M/NOPB

Part Overview

The LM4892M/NOPB is a linear amplifier integrated circuit manufactured by Texas Instruments, categorized under Class AB mono amplifiers. It is designed for 1-channel (mono) audio output with an integrated mono headphone amplifier, supporting a supply voltage range of 2.2V to 5.5V. The device offers output power ratings of 1W x 1 @ 8Ω and 90mW x 1 @ 32Ω, featuring Depop, Shutdown, and Thermal Protection functions. Packaged in an 8-SOIC surface-mount package, this product is currently classified as obsolete. Due to its part status, identifying a substitute with equivalent electrical and mechanical parameters is necessary for form, fit, and function compatibility in existing and new designs.

Engineering Selection Recommendations

Selection between LM4892M/NOPB and LM4890M/NOPB is based on product availability and regulatory compliance. LM4892M/NOPB is obsolete and not recommended for new designs. LM4890M/NOPB is active, available, and maintains compliance with RoHS3, REACH, and MSL 1 requirements.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for selecting a substitute for the LM4892M/NOPB?
A1: Substitute parts must match the type (Class AB), output configuration (1-channel mono), maximum output power at the specified load, supply voltage range, feature set, mounting type, package size, operating temperature range, and be compliant with RoHS3, REACH, and MSL 1 standards.

Q2: Is LM4890M/NOPB drop-in compatible with LM4892M/NOPB in the same 8-SOIC footprint?
A2: Yes. Both devices use the 8-SOIC (0.154", 3.90mm width) surface-mount package.

Q3: Does the status of the part affect its suitability for new designs?
A3: Yes. LM4892M/NOPB is obsolete, while LM4890M/NOPB is active and available, making it more suitable for ongoing and future designs.

Q4: Are there any differences in certifications or compliance between the two parts?
A4: Both devices are RoHS3 compliant, meet REACH requirements, and have MSL 1 (unlimited) ratings.

Q5: Are the functional features (Depop, Shutdown, Thermal Protection) present in both parts?
A5: Yes. Both LM4892M/NOPB and LM4890M/NOPB include these features as specified.
