Handler Implementation Notes

Package Code Extraction

// AD package codes appear AFTER grade letter
// Example: AD8065ARZ -> base="AD8065", grade="A", package="R", rohs="Z"

// Common package code mappings
switch (packageCode) {
    case "R" -> "SOIC";
    case "RM" -> "MSOP";
    case "RU" -> "TSSOP";
    case "RZ" -> "QFN";
    case "RT" -> "SOT-23";
    case "T" -> "LQFP";
    case "CP" -> "LGA";
    case "BCCZ", "CCZ" -> "LGA";  // Accelerometer packages
    case "N", "P" -> "PDIP";
    case "H" -> "TO-52";
}

// IMPORTANT: Strip trailing "Z" (RoHS indicator) before package lookup
// AD8065ARZ -> package is "R" (SOIC), not "RZ" (QFN)
String pkg = mpn.replaceAll("Z$", "").replaceAll(".*[A-Z](R[A-Z]*)$", "$1");

Series Extraction

// Most AD parts: prefix + numeric series
// AD8065ARZ -> series = "AD8065"
// ADXL345BCCZ -> series = "ADXL345"

// OP series: "OP" + 2 digits
// OP27GPZ -> series = "OP27"

// Strip grade, package, and RoHS suffixes
String series = mpn.replaceAll("[A-Z]{1,4}Z?(-R[L7])?$", "");

Critical Pattern Issues

1. AD8xxx vs AD5xxx vs AD7xxx confusion:

   • AD8xxx = Op-amps/amplifiers
   • AD5xxx = DACs
   • AD7xxx = ADCs (precision)
   • AD9xxx = ADCs (high-speed)

2. ADT vs AD590 temperature sensors:

   • ADT = Digital temperature sensors
   • AD590 = Analog current-output sensor

3. Single/Dual/Quad variants:

   • Often differ by last digit: AD8065 (single), AD8066 (dual)
   • Or by middle digits: AD8605/AD8606/AD8608

• Component types: OPAMP_AD, ADC_AD, DAC_AD, AMPLIFIER_AD, VOLTAGE_REFERENCE_AD, TEMPERATURE_SENSOR_AD, ACCELEROMETER_AD, GYROSCOPE_AD
• Package registry: PackageCodeRegistry.java (standard codes)

Known Handler Issues

1. HashSet in getSupportedTypes(): Should use Set.of() or EnumSet for immutability
2. Missing ADC/DAC patterns: No patterns registered for AD7xxx (ADCs) or AD5xxx (DACs) with manufacturer-specific types
3. Generic IC fallback: ADCs and DACs fall through to generic ComponentType.IC instead of ADC_AD/DAC_AD
4. Package extraction bug: Current logic doesn't properly handle the grade+package+rohs structure

Learnings & Edge Cases

• RoHS suffix "Z": Almost all modern AD parts end with "Z" for RoHS compliance - don't confuse with package code
• Single/Dual naming: AD8065=single, AD8066=dual (differ by last digit)
• OP series grades: OP27E (commercial), OP27G (industrial) - letter comes right after series number
• ADXL accelerometers: Use "BCCZ" and "CCZ" for LGA packages, unique to MEMS products
• AD590 is special: Very old design, uses TO-52 metal can ("H" suffix), current output (1uA/K)
• Linear Technology merger: LTC parts now under AD umbrella, use different suffix convention (#TRPBF)
