Maxim Integrated MAX873ACSA+T Voltage Reference

The MAX873ACSA+T from Maxim Integrated is a precision voltage reference designed for use in a wide array of applications requiring a stable and accurate voltage source. This component is part of Maxim’s family of low-power, high-precision voltage references, and it stands out due to its ease of use and reliable performance across various conditions.

The MAX873ACSA+T offers a fixed output voltage of 2.5V, with an impressive temperature coefficient of only 20ppm/°C (max) over the full automotive temperature range (-40°C to +125°C). This ensures that the voltage remains consistent and precise, even when subjected to temperature variations, making it ideal for high-precision applications.

With a low supply current of just 150µA (max) and the ability to source or sink up to 5mA of load current, this voltage reference is optimized for battery-powered and energy-efficient systems. The low dropout voltage of the device allows it to function correctly even when the supply voltage is very close to the output voltage, further enhancing its suitability for systems with limited power headroom.

The MAX873ACSA+T is packaged in a compact 8-pin SOIC form factor, making it suitable for space-constrained applications. Its small size, combined with the no external components required for operation, simplifies design and saves valuable board space.

This voltage reference also features a force and sense connection that allows for remote voltage sensing, compensating for any voltage drop due to the resistance of the PCB traces. This feature is particularly useful in precision applications where voltage drops can significantly affect performance.

Applications for the MAX873ACSA+T are diverse and include A/D and D/A converters, portable instrumentation, battery chargers, and power supplies. Its reliability and stability make it a go-to choice for engineers and designers looking for a reference voltage that they can set and forget.

In summary, the Maxim Integrated MAX873ACSA+T is a versatile, high-precision voltage reference that offers stable performance, low power consumption, and a small footprint, making it an excellent choice for a wide range of applications.
