The LM4041AIM3-1.2+T is a precision shunt voltage reference designed to meet the requirements of high-precision applications. It is part of the extensive range of precision voltage references offered by Texas Instruments. The device is packed in the SOT-23-5 form factor package and its function is to provide a stable, low temperature-coefficient voltage reference which is a primary basis for accurate voltages regulatory operations in a broad range of power management and microprocessor-based applications.
Part of the precision voltage references family, LM4041AIM3-1.2+T is a shunt voltage reference device that is part of the PMIC (Power Management Integrated Circuit) voltage reference family. It offers low temperature drift, low noise, and high output current performance. The device is ideal for supplying a stable voltage reference for many digital-to-analog and analog-to-digital conversion systems, voltage regulators, data converters, and other precision control systems.
At the heart of LM4041AIM3-1.2+T is an advanced, low-drift, on-chip voltage reference cell. The reference cell is designed to provide a low-output temperature coefficient (TC) and to maintain a high output voltage stability over temperature changes. The LM4041AIM3-1.2+T also offers low noise, high accuracy and a highly stable output voltage level.
The LM4041AIM3-1.2+T is designed to provide an output voltage of 1.2V with an initial accuracy of 0.2%, and a low-temperature coefficient of the output voltage of 0.1%/°C over the operating temperature range. The typical line regulation is 20 ppm/V and typical load regulation is 30 ppm/mA. With a rail-to-rail output capability, the device can offer a wide operating range from 1V to 36V and is capable of supplying up to 20mA of current with short-circuit protection.
The LM4041AIM3-1.2+T has two-term adjustable current sources. One can be trimmed to match the output with the reference cell, the other term is decoupled to reduce noise. The device also includes an on-chip low-impedance error amplifier, which helps minimize the effect of power supply noise on the output voltage.
The LM4041AIM3-1.2+T offers excellent temperature stability and low noise performance. With an output noise of 0.5μV RMS and a dropout voltage of 46mV, the device is ideal for precision power management applications requiring high accuracy, low power consumption and zero external components.
The LM4041AIM3-1.2+T also integrates a temperature monitoring pin that provides an output current proportional to the device\'s temperature to help prevent possible damages due to overheating. The device is also offered in an 8-pin SOIC package with thermal pad, allowing for lower thermal resistance connection to ground.
In conclusion, the LM4041AIM3-1.2+T is a precision shunt voltage reference device specifically designed to meet the demanding requirements of applications requiring high precision and low temperature coefficient. It offers excellent accuracy and noise performance, as well as low-temperature drift and stable reference over temperature and line trends. These properties make the LM4041AIM3-1.2+T the perfect choice for many power management, microprocessor-based, and precision control applications requiring a stable and low temperature-coefficient voltage reference.
