MAX6037BAUKADJ+T

Introduction

The MAX6037BALKADJ+T is a precision adjustable voltage reference from Maxim Integrated Products. It is a unique reference design in that it offers a low quiescent current of only 150µA compared to other reference designs with a quiescent current of up to 450µA. The MAX6037BAUKADJ+T is ideal for automotive, industrial, and consumer applications, where low quiescent current is a must.

Application Field

The MAX6037BAUKADJ+T is designed be an ideal reference solution for automotive, industrial, and consumer applications. It provides an adjustable voltage range up to 6 volts with an accuracy of ± 0.2% (1.2mV) across the safety temperature range of -40°C to +125°C. This voltage reference is capable of sourcing and sinking current up to 30mA with low ripple and noise. It is optimized to provide reliable and accurate initial accuracy over a wide temperature range.

The MAX6037BAUKADJ+T is also designed with EMI and ESD immunity for automotive and consumer applications. With a low quiescent current, the MAX6037BAUKADJ+T can reduce the power consumption of the system, and also provide a longer battery life for the product. It is offered in a small SOT23-6 package, which is ideal for portable and consumer applications.

Working Principle and Block Diagram

The MAX6037BAUKADJ+T is an adjustable voltage reference that operates on the principle of a bandgap reference. It is made up of three main blocks: the voltage reference, the voltage divider and the current divider. The voltage reference section provides a precise reference voltage, typically 1.20V but adjustable up to 6V. The voltage divider reduces the reference voltage to a lower level, while the current divider adjusts the current to keep the reference voltage constant. The reference voltage is then outputted from the voltage reference pin.

The MAX6037BAUKADJ+T block diagram is presented in figure 1 for a better understanding of its components and operation. The device includes an on-board voltage reference, voltage divider and current divider, a precision amplifier and a current sinks. The reference pins of the IC gives access to the reference voltage, which is the voltage which is used to bias the amplifier. The reference voltage is then adjusted using the voltage divider and the current divider, which can be programmed using external resistors. The output of the amplifier is then delivered to the output pins, where it can be monitored.
