LM4040 Voltage Reference Module

The LM4040 Voltage Reference Module is a high-precision, low-power shunt voltage reference designed for applications requiring stable and accurate voltage sources. It utilizes the LM4040 IC, which provides fixed output voltages such as 2.048V, 2.5V, 3V, 4.096V, 5V, 8.192V, and 10V with tight tolerances (as low as ±0.1% for A-grade versions). This module is built around the LM4040 shunt reference, which operates by regulating voltage through a shunt path, making it suitable for low-current applications. Key features include a wide operating temperature range of -40°C to +125°C, low output noise (typically 35 μVrms from 10 Hz to 10 kHz), and minimal operating current (starting from 60 μA). It is commonly used in analog-to-digital converters (ADCs), digital-to-analog converters (DACs), power supply monitoring, and battery-powered devices due to its micropower consumption. Buyers should choose this module for its reliability, precision, and ease of integration in Indian electronics projects, offering excellent value for hobbyists and professionals alike. The module typically includes the LM4040 IC in a compact SOT-23 or TO-92 package, ensuring compatibility with various circuits.
