Engineering Selection Recommendations

The LPV321M7X/NOPB is a direct functional and mechanical equivalent of the LPV321M7X. Selection between these parts is determined by product availability and supply chain status:

LPV321M7X (Texas Instruments): Obsolete status restricts availability to existing inventory. This part number is suitable only for replacement or repair of existing assemblies where original component matching is required.

LPV321M7X/NOPB (National Semiconductor): Active product status ensures ongoing availability and supply chain continuity. This variant is the preferred selection for new designs, production builds, and long-term applications requiring component reliability and procurement stability.

Both parts maintain identical electrical performance and package configuration, enabling direct substitution without circuit redesign or PCB layout modification. Selection should prioritize the active part number for applications requiring sustained production support.

Frequently Asked Questions (FAQ)

Q: Can LPV321M7X/NOPB replace LPV321M7X in existing designs?

A: Yes. The LPV321M7X/NOPB is electrically and mechanically equivalent. All electrical parameters, including slew rate, gain bandwidth product, supply current, and output current, are identical. The SC-70-5 package configuration is unchanged, requiring no PCB layout modifications.

Q: What is the difference between LPV321M7X and LPV321M7X/NOPB?

A: The primary difference is product status and manufacturer designation. LPV321M7X is obsolete; LPV321M7X/NOPB is active. The "/NOPB" suffix indicates lead-free, RoHS-compliant packaging. Electrical specifications are identical.

Q: Are there any compliance or certification differences?

A: Both parts share identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications. Compliance status is equivalent for export and regulatory purposes.

Q: What supply voltage range does this amplifier support?

A: The LPV321M7X and LPV321M7X/NOPB operate across a 2.7V to 5V supply voltage range, suitable for single-supply and dual-supply configurations in low-power applications.

Q: Is the SC-70-5 package suitable for automated assembly?

A: Yes. Both parts use the SC-70-5 (5-TSSOP / SOT-353) surface mount package, which is compatible with standard pick-and-place and reflow soldering processes.

Q: What is the maximum output current per channel?

A: The maximum output current is 60 mA per channel, suitable for driving moderate loads and interfacing with standard logic circuits.
