The ADR291GRUZ is a high-precision, low-power voltage reference from Analog Devices Inc. that offers a stable output voltage of 2.5V. Designed for space-constrained and power-sensitive applications, this device is part of a family of micropower, series voltage references which operate at a low 3 µA (typical) up to 5 µA (maximum) supply current.

Featuring a wide input voltage range from 4V to 12V, the ADR291GRUZ maintains a high accuracy with a maximum temperature coefficient of 10 ppm/°C over the industrial temperature range (-40°C to +85°C). This ensures reliable performance under varying environmental conditions, making it suitable for precision data conversion systems, battery-powered and portable instruments, and industrial process control systems.

One of the key advantages of the ADR291GRUZ is its low output noise of 17 µV peak-to-peak (0.1 Hz to 10 Hz), which makes it an excellent choice for applications requiring a low noise power supply. Additionally, the device features a low dropout voltage, which further enhances its suitability for battery-operated devices where the supply voltage may vary over time.

The ADR291GRUZ is available in a compact TSSOP-8 package, providing an excellent space-saving solution without compromising on performance. Its robust design also includes a temperature hysteresis of 150 ppm typical, ensuring stable output even with temperature cycling.

As with all Analog Devices products, the ADR291GRUZ is designed with reliability in mind. It is short-circuit and reverse battery protected, ensuring a long operational life and resilience in the face of potential wiring issues. This product is ideal for engineers looking for a stable voltage reference that combines high precision with low power consumption and minimal footprint.
