The AD1582BRT from Analog Devices Inc. is a high-precision, low-power, series voltage reference in a compact SOT-23 package. This device is part of a family of pin-compatible voltage references, offering a fixed 2.5V output with a tight initial accuracy of ±0.1% and excellent temperature stability.

Designed to be versatile and robust, the AD1582BRT is suitable for high-performance data converters, portable instrumentation, and industrial applications where space is at a premium and power efficiency is crucial. With a low operating current of just 500 µA (maximum) and a wide operating temperature range from -40°C to +125°C, it is an ideal choice for demanding environments.

The AD1582BRT boasts a low dropout voltage, typically 200 mV at 1 mA load, which allows for efficient operation even with minimal headroom above the output voltage. This feature, coupled with a low output noise of 10 µV p-p (0.1 Hz to 10 Hz), makes it an excellent choice for precision analog circuits.
