The LM4041DEM3-ADJ is part of the precision micropower voltage reference family from Texas Instruments. The device features an Autocalibration mechanism guarantee 2% initial accuracy over the full temperature range, improved load regulation and fast settling time. This micropower voltage reference ensures a low supply current for battery-powered applications and offers a low-tempco performance ideal for temperature-sensitive systems. Additionally, the LM4041DEM3-ADJ provides excellent line and load regulation, exceeding the specifications of discrete Zener references.

This voltage reference is tailored for battery-powered, low-power applications, suitable for both hand-held and consumer gadgets. With its Autocalibration mechanism, the LM4041DEM3-AD3 emphasizes on low-power and low-temperature performance. With the ability to adjust its output voltage in the range of 1.225 V to 25 V with excellent accuracy, the device is suitable for recharging and monitoring apps that require precision control and consistency. Thus, enabling power savings as the device will only use up 75-90 μA of trickle current when active.

The LM4041DEM3-ADJ enables higher power efficiency than discrete Zener references. It can withstand a maximum of 35V line transient and still maintain accuracy and line regulation better than those available on the market, for example the TL431. Additionally, the LM4041DEM3-ADJ features a fast settling time of 20μs to within 0.2% of its maximum output voltage, making it ideal for data-transmission line and audio-amplifier applications.

The LM4041DEM3-ADJ device is available in three output voltage options of 1.225V, 2.5V and 4.096V with high accuracy of ±2%. It comes in an easy to use 3-pin SOT23-3 DMP package which allows for optimum thermal and electrical performance. A single version of the device allows for the complete adjustment of the output voltage which follows an adjustment range from 1.225V to 25V. Additionally, it features a temperature coefficient of -25V/°C, allowing it to maintain its accuracy over a wide temperature range from -40°C to 125°C.

The LM4041DEM3-ADJ combines Dynamic Autocalibration, low power and wide temperature range, allowing it to meet the requirements of industrial, telecom, process control and automotive applications. Using the Dynamic Autocalibration technique guarantees initial accuracy, low-power and low temperature operation, while its excellent line regulation, load regulation and fast-settling time all make it suitable for various application fields, such as in power supplies monitoring and battery-powered systems.

In conclusion, the LM4041DEM3-ADJ combines Autocalibration, initial accuracy, low-power and wide temperature range, making it an ideal choice for a wide variety of low-power precision application fields such as industrial, automotive, telecommunications and process control. With its adjustable output voltage range from 1.225 V to 25V, a maximum transient rating of 35V, excellent line and load regulation, and fast settling time, the LM4041DEM3-ADJ is an excellent choice for designers looking for a low-power voltage reference for their projects.
