Maxim Integrated MAX6125ESA+ Voltage Reference

The MAX6125ESA+ is a high-precision, low-noise, micropower voltage reference from Maxim Integrated, designed to provide a stable and accurate reference voltage for high-performance analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and other precision analog circuitry. This device is particularly suitable for battery-powered and portable applications due to its low power consumption and compact footprint.

With an output voltage of 2.5V, the MAX6125 offers excellent temperature stability and low noise performance, ensuring reliable operation across a wide range of environmental conditions. The voltage reference is capable of sourcing and sinking current, making it versatile for various circuit configurations.

Key Features:

• High Accuracy: The MAX6125ESA+ boasts an initial accuracy of ±0.02% (max) and a temperature coefficient of just 3ppm/°C (max), providing precise voltage regulation for critical applications.
• Low Power Consumption: With a quiescent current of only 125µA (max), this device is optimized for power-sensitive designs.
• Low Dropout Voltage: The dropout voltage is minimal, typically 100mV at full load, which allows for efficient operation even with low input voltages.
• Wide Operating Temperature Range: The MAX6125ESA+ is designed to perform reliably over an industrial temperature range of -40°C to +85°C.
• Stable with Capacitive Loads: This voltage reference can drive capacitive loads up to 2.2µF, offering design flexibility and ease of use.
• Compact Package: The device comes in a space-saving 8-pin SOIC package, ideal for applications where board space is at a premium.

The MAX6125ESA+ also includes a force and sense connection that allows for remote voltage sensing, compensating for voltage drops in wires or PCB traces to ensure the accuracy of the voltage delivered to the load. This feature is especially useful in precision applications where voltage drops cannot be tolerated.

Whether you're designing precision instrumentation, portable medical devices, or any other application requiring a high-accuracy voltage reference, the MAX6125ESA+ from Maxim Integrated is an excellent choice that combines performance, reliability, and efficiency.
