The R5F11TLGDFB#30 supports LCD configurations up to 42 segments and 8 commons. Its integrated LCD controller offers internal voltage boosting, capacitor split, and external resistor division methods - eliminating need for external bias generators in most meter display designs.
How many analog input channels does the R5F11TLGDFB#30 provide?
The R5F11TLGDFB#30 provides four 24-bit ΔΣ A/D converter channels (ANIP0–ANIP3/ANIN0–ANIN3) plus four 10-bit SAR A/D converter channels (ANI0–ANI3), with dedicated AVREFP/AVREFM pins for high-precision voltage referencing in metrology applications.
Is the R5F11TLGDFB#30 qualified for industrial temperature operation?
Yes, the R5F11TLGDFB#30 is rated for industrial temperature operation from −40°C to +85°C. Its "D" suffix in the part number explicitly denotes industrial-grade qualification, ensuring reliable performance in outdoor meter enclosures and uncontrolled electrical cabinets.
