# Industrial Specification: Signal Processing Circuitry

## 1. Technical Definition
Electronic circuitry that processes analog signals from line scan camera sensors into digital data

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-5 VDC input, 0-3.3 VDC output, -40°C to +85°C ambient**. Failure boundary: **Input voltage exceeding 5.5 VDC causes op-amp saturation, output voltage exceeding 3.6 VDC damages downstream ADCs, ambient temperature exceeding 125°C causes semiconductor junction breakdown**, Mechanism: **Semiconductor thermal runaway at 125°C due to increased leakage current (doubling every 10°C per Arrhenius equation), op-amp rail-to-rail limitation at 5.5 VDC causing signal clipping, ADC reference voltage tolerance of ±0.1% at 3.3 VDC**.
