1. Description

️· The LS832 is a dual N-channel JFET (Junction Field-Effect Transistor). It's designed for applications requiring low noise and high linearity. It's part of the Micross Components product line.

2. Key Features

️· Low Noise: Optimized for low noise applications.
️· High Linearity: Good linearity performance.
️· Matched Characteristics: The dual JFETs are matched, referring to parameters like gate-gate voltage and drain-drain leakage. This is crucial for balanced circuits.
️· Wide Operating Range: Operates across a wide range of temperatures (specified as -55°C to +125°C for some characteristics).
️· Common Mode Rejection: Good common-mode rejection, important for differential applications.

3. Electrical Characteristics (Most Important Values)
