# Industrial Specification: ADC Circuit

## 1. Technical Definition
Electronic circuit that converts analog signals to digital data within a Data Acquisition Unit.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-5 V input, 0-3.3 V supply, -40°C to +85°C ambient**. Failure boundary: **Input voltage exceeding 5.5 V causes comparator saturation, sampling rate dropping below 100 kSPS introduces aliasing, supply voltage below 2.7 V triggers brownout reset**, Mechanism: **Dielectric breakdown in MOSFET switches at &gt;5.5 V input, thermal noise exceeding quantization step at high temperatures, electromigration in aluminum interconnects at &gt;85°C**.

### 2.1 Analytical Physics Model
Governed by the **Joule Heating & Thermal Resistance**:

> **Primary Equation**: $P = I^2 R = \frac{V^2}{R}$  
> **Engineering Impact**: Governs heating element sizing for shrink tunnels/sealers.
