LM4040AIM3X-4.1/NOPB – TEXAS INSTRUMENTS

The LM4040AIM3X-4.1/NOPB is a Texas Instruments precision shunt voltage reference featuring a 4.1V output voltage. This specific part number denotes a surface-mount device (SMD) in a SOT-23-5 package (3x3mm), signifying its suitability for space-constrained applications. The “AIM3X” indicates a specific manufacturing process and quality grade, guaranteeing tighter tolerance and improved stability compared to lower-grade variants. Its output voltage tolerance is typically ±0.5% at 25°C, with a temperature coefficient of ±20ppm/°C, ensuring high accuracy over a wide operating temperature range._x000D_

The device operates over a supply voltage range of 4.5V to 26V, drawing a low quiescent current, typically less than 150µA. Its low noise characteristics (typically less than 10µVrms) make it ideal for applications requiring a clean and stable voltage reference. Common use cases include precision analog-to-digital converters (ADCs), instrumentation amplifiers, and voltage comparators where accurate voltage thresholds are critical. The LM4040AIM3X-4.1/NOPB’s lead-free (“NOPB”) packaging complies with RoHS standards and contributes to environmentally friendly designs. Its small size, high accuracy, and low noise make it a superior choice in space-constrained high-precision applications compared to larger, less accurate alternatives.
