# Industrial Specification: Readout Circuit

## 1. Technical Definition
Electronic circuit that processes and converts signals from detector elements into usable data.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-5.0 V input signal range, -40°C to +85°C ambient temperature**. Failure boundary: **Input voltage exceeding 5.5 V causes op-amp saturation, signal-to-noise ratio dropping below 20 dB at -45°C**, Mechanism: **Semiconductor junction breakdown at 5.5 V forward bias, carrier mobility reduction below -40°C causing thermal noise dominance**.

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

> **Primary Equation**: $P = I^2 R = \frac{V^2}{R}$
