# Industrial Specification: ADC Converter

## 1. Technical Definition
Electronic device that converts continuous analog signals into discrete digital values for processing by digital systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-5 VDC input, -40°C to +85°C ambient temperature, 0-100% relative humidity (non-condensing)**. Failure boundary: **Input voltage exceeding 5.5 VDC causes permanent damage to input protection diodes, ambient temperature exceeding 125°C causes silicon junction thermal runaway, sampling frequency exceeding Nyquist limit (2×max analog frequency) causes aliasing distortion**, Mechanism: **Semiconductor junction breakdown at 5.5 V reverse bias voltage (silicon PN junction avalanche effect), thermal carrier generation exceeding recombination rate at 125°C (Arrhenius equation with Ea=0.7 eV), Shannon-Nyquist sampling theorem violation when fs &lt; 2fmax**.

### 2.1 Analytical Physics Model
Governed by the **Combined Measurement Uncertainty**:
