How can I request samples and evaluation boards?
Samples and evaluation boards can be requested through LiTong Electronics. Submit sample requests through our website with your company information, project description, and required quantities. Standard sample quantities are 2-5 pieces per part number for evaluation purposes. Evaluation boards for key products and solutions are available for purchase or loan depending on the program. University and research institutions may qualify for free samples through our educational program. Sample requests are typically processed within 1-2 business days and shipped via standard courier. For production prototypes requiring larger quantities, contact your sales representative to discuss options. Custom evaluation boards for specific applications can be developed upon request with minimum order quantities.
Submit your sample request through the LiTong website. Include your project timeline and production forecast for priority processing.
What is the quality and reliability of Gainsil products?
Gainsil products undergo rigorous quality and reliability testing to ensure consistent performance. All products are manufactured at TSMC using qualified processes with statistical process control. Electrical testing includes parametric verification at room temperature and guard band testing for key parameters. Reliability qualification includes High Temperature Operating Life (HTOL), Temperature Cycling (TC), High Temperature Storage (HTS), and Electrostatic Discharge (ESD) testing. Products meet or exceed JEDEC standards for integrated circuit reliability. Automotive-grade products are qualified to AEC-Q100 standards with additional testing. Quality certifications include ISO 9001:2015 for quality management systems. Reliability data and qualification reports are available upon request. Field failure rates are monitored and typically below 50 ppm for mature products.
Request qualification reports and reliability data for your specific application requirements. Automotive products include full PPAP documentation.
How do I report a technical issue or product defect?
Technical issues and potential product defects should be reported to LiTong Electronics for investigation. Submit detailed problem descriptions through our technical support portal including part numbers, date codes, failure symptoms, and application conditions. Provide schematics and PCB layouts for design-related issues. Include oscilloscope captures, measurement data, and photos if applicable. For potential defects, return failed units with RMA (Return Material Authorization) for failure analysis. Our FA team will conduct electrical testing, X-ray inspection, and decapsulation if necessary to determine root cause. Investigation results are typically provided within 5-10 business days depending on complexity. Corrective actions are implemented for confirmed defects. 8D reports are provided for major quality issues. Field alert notifications are issued for safety-critical defects.
Report issues promptly with detailed information to expedite investigation. Contact your sales representative immediately for production line stoppages.
What is the typical lead time for Gainsil products?
Standard lead times for Gainsil products range from 8 to 12 weeks for factory orders, depending on the specific product and order quantity. LiTong maintains strategic inventory of high-demand Gainsil products, enabling immediate shipment for many popular part numbers. For volume production requirements, we recommend establishing a forecast and scheduled delivery agreement to secure capacity and optimize inventory management. Rush orders and expedited delivery options are available for urgent requirements, subject to factory capacity. LiTong's supply chain team monitors Gainsil's production schedule and proactively communicates any lead time changes to affected customers. Contact your sales representative for current lead time information on specific products.

LiTong can provide detailed qualification reports and PPAP documentation for automotive customers requiring full traceability and quality documentation.
For automotive applications, specify AEC-Q100 qualified Gainsil products and request qualification documentation from LiTong.
How do I choose between different Gainsil op-amp families?
Gainsil offers several op-amp families optimized for different applications. The GS85xx series provides ultra-low offset voltage (50μV max) for precision DC applications like sensor signal conditioning. The GS86xx family offers low power consumption for battery-operated devices. For general-purpose applications, the GS85xx series provides excellent bandwidth and precision balance. Consider your primary requirements: For precision DC measurements, prioritize offset voltage and drift specifications. For AC applications, focus on gain bandwidth product and slew rate. For battery-powered designs, evaluate quiescent current and rail-to-rail operation. For wide temperature range applications, check drift specifications and temperature range. Each family datasheet provides detailed specifications to help match the optimal product to your application requirements.
