MPN Structure

Analog Devices MPNs follow this general structure:

[PREFIX][SERIES][GRADE][PACKAGE][ROHS][REEL]
   |       |       |       |       |      |
   |       |       |       |       |      +-- Optional: -R7=7" tape, -RL=large reel
   |       |       |       |       +-- Z = RoHS compliant
   |       |       |       +-- Package code (R, RU, RZ, etc.)
   |       |       +-- Temperature/performance grade (A-G, J, K, etc.)
   |       +-- Series number (e.g., 8065, 7606, 590)
   +-- Family prefix (AD, OP, REF, AMP, ADXL, etc.)

Example Decoding

AD8065ARTZ-R7
|   |   ||||  |
|   |   ||||  +-- R7 = 7" tape and reel
|   |   |||+-- Z = RoHS compliant
|   |   ||+-- T = SOT-23 package (5-pin)
|   |   |+-- R = Surface mount
|   |   +-- A = -40C to +85C industrial grade
|   +-- 8065 = High speed FET input op-amp series
+-- AD = Analog Devices prefix

ADXL345BCCZ-RL
|   |   |  ||  |
|   |   |  ||  +-- RL = Large tape and reel
|   |   |  |+-- Z = RoHS compliant
|   |   |  +-- CC = LGA package
|   |   +-- B = Variant (improved specs)
|   +-- 345 = 3-axis digital accelerometer
+-- ADXL = Accelerometer family prefix

AD7606BSTZ
|   |   |||
|   |   ||+-- Z = RoHS compliant
|   |   |+-- T = LQFP package
|   |   +-- S = industrial temp, LQFP
|   +-- 7606 = 8-channel simultaneous sampling ADC

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)
