LM4040BIM3-4.1 TI Precision Micropower Shunt Voltage Reference | SOT-23-3 | 4.096V, ±0.2%

Product Overview

The LM4040BIM3-4.1 from Texas Instruments is a high-precision, micropower, shunt voltage reference designed for space-constrained applications. It provides a fixed 4.096V output with an initial accuracy of ±0.2% and a low temperature coefficient of 100 ppm/°C (max). Housed in a compact SOT-23-3 package, it operates over a wide current range from 60 µA to 15 mA, making it ideal for battery-powered and portable equipment. The device requires no external capacitor for stability and offers excellent long-term stability and low noise.
