Package

The LT1373CS8 is packaged in an 8-lead SOIC (Small Outline Integrated Circuit) configuration. This surface-mount package is designed for efficient thermal performance and space-saving on printed circuit boards.

Pinout

The LT1373CS8 is an integrated circuit from Analog Devices, specifically designed as a high-speed comparator. It features an 8-pin configuration (DIP or SOIC package).
Pin Count and Functions:
1. Pin 1 (Inverting Input): The input where the reference voltage is applied.
2. Pin 2 (Non-Inverting Input): The input where the signal voltage is applied.
3. Pin 3 (V- or Ground): Negative supply voltage or ground reference.
4. Pin 4 (Output): The comparator output signal, indicating whether the non-inverting input is greater than the inverting input.
5. Pin 5 (V+ or Supply Voltage): Positive supply voltage.
6. Pin 6 (Compensation): Provides external compensation for stability.
7. Pin 7 (Noise Bypass): For bypassing noise; typically connected to a capacitor.
8. Pin 8 (No Connect): Not used, can be left open.
The LT1373 offers high speed, low offset voltage, and is suited for applications requiring fast response times.
