FAQ
Q1: What’s the difference between a distributor and a manufacturer when buying amplifier ICs?
A: A manufacturer (ST, Infineon, Cedrat) designs and produces ICs. Distributors (Unit Electronics, Jameco, SIC) buy and resell parts — they add logistics, inventory and local support. For guaranteed authenticity and lifecycle support, buying through authorized distributors or directly from the manufacturer is best.
Q2: How do I verify amplifier IC authenticity from an independent distributor?
A: Ask for traceability paperwork, batch/lot numbers, and test reports. Reputable independent distributors offer factory documentation, X-ray or de-cap test results on request.
Q3: Which amplifier IC family is best for portable battery audio?
A: Class-D amplifier ICs are typically the best due to high efficiency; Infineon’s MA / MERUS family and TI class-D parts are common choices.
Q4: I need an obsolete LM386 equivalent — where should I look?
A: Check hobbyist and legacy-part sellers (Jameco) for single units, and specialized independent distributors (HK Rongyu, SIC) for larger lots with traceability; always sample and test before production.
Q5: Can Cedrat replace a general audio amplifier IC in my design?
A: Not directly — Cedrat focuses on piezo drivers and precision actuator amplifiers. If you need specialized high-voltage piezo drivers or motion control, Cedrat is appropriate; for general audio power amps, choose audio-focused IC vendors/distributors.
Q6: How should I list amplifier part alternatives in my BOM?
A: Provide a primary part, a form-fit-function alternative (pin-compatible if possible), and a cross-vendor alternative (different vendor but same specifications). Include manufacturer P/N, distributor stock links, and MOQ/lead time notes.
