AD1580ART Voltage Reference by Analog Devices Inc.

The AD1580ART is a high-precision, low-power, series voltage reference from Analog Devices Inc., designed for a broad spectrum of applications. This compact and robust component comes in a space-saving SOT-23 package, making it an excellent choice for portable and battery-powered equipment where space is at a premium.

With a fixed output voltage of 1.2V, the AD1580ART provides a stable reference voltage with an impressive initial accuracy of ±0.1%. Its low dropout voltage and low quiescent current make it particularly suitable for low voltage, high precision systems. The device operates with a supply voltage range from 2.0V to 12.6V, consuming a minimal quiescent current of 60 µA, which is ideal for power-sensitive applications.

One of the standout features of this voltage reference is its low temperature coefficient, typically 30 ppm/°C, ensuring consistent performance over a wide operating temperature range of -40°C to +85°C. This makes the AD1580ART a reliable choice for systems that require high stability across diverse environmental conditions.

The AD1580ART is not only characterized by its high precision but also its excellent load regulation and low output noise, which are critical for high-resolution analog-to-digital and digital-to-analog conversions. This device is also trimmed during the manufacturing process for low output voltage hysteresis, which is essential for applications that demand a stable voltage reference even after multiple power cycles.

In summary, the AD1580ART from Analog Devices Inc. is a superior choice for engineers and designers looking for a reliable, low-power voltage reference that doesn't compromise on precision. Whether it's integrated into data acquisition systems, portable instrumentation, or medical devices, the AD1580ART stands out for its stability, accuracy, and power efficiency.
