Sourcing Guidance
ADC0804LCN is a legacy or obsolete orderable code. Source only with date-code, label, package and traceability checks appropriate to the application.
For an accurate quotation, include the full MPN, target quantity, acceptable date-code range, packaging format and destination. Icearth can help review traceability documents, label photos and electrical/package alignment before order placement.
Manufacturer Documentation
Technical values were checked against Texas Instruments documentation. Use the linked datasheet as the controlling source and re-check revisions before PCB release or firmware qualification.
ADC0804LCN selection and design context
ADC0804LCN is cataloged as a Analog-to-Digital Converter in the ADC0804-N family. Its recorded function is 8-bit microprocessor-compatible successive-approximation analog-to-digital converter. Selection should be based on the complete electrical limits, package drawing and ordering suffix rather than the abbreviated family code.
- Resolution: 8 bit. Use the worst-case datasheet limit rather than a typical headline value.
- Supply Voltage: 4.5 V to 5.5 V recommended. Check rail compatibility, tolerance and sequencing under worst-case conditions.
- Typical Conversion Time: 103 µs at 640 kHz. Confirm the value and its datasheet test conditions for the exact ordering suffix.
- Analog Input: Differential, nominal 0 V to 5 V span. Confirm the value and its datasheet test conditions for the exact ordering suffix.
Application and qualification considerations
When evaluating this power device, confirm input range, output requirements, switching frequency, compensation, current limit, efficiency and thermal design. For a new design, review power-up behavior, interface timing, absolute maximum ratings, thermal limits and any external-component requirements in the latest manufacturer documentation. Existing-board replacement work should additionally confirm pinout, footprint, firmware assumptions and qualification grade.
Procurement checks for ADC0804LCN
The recorded package is 20-lead PDIP, the temperature range is 0°C to +70°C, and the lifecycle status is Obsolete as of 2026-07-18. Before ordering, confirm the exact MPN on the label, packing format, quantity, date-code requirements, traceability documents and current factory status.
ADC0804LCN FAQ
