Voltage references are a type of integrated circuit (IC) that provide a constant voltage. They are used in a variety of applications, such as power supplies and analog-to-digital converters. The ADR02AR-REEL is a precision micropower voltage reference with a low temperature coefficient and low power consumption. It is designed to be used in space-constrained applications, such as hand-held devices and portable medical electronics.

The working principle of the ADR02AR-REEL involves a single resistor, a bandgap reference source, and a voltage amplifier. The resistor is connected in series between the supply voltage and the bandgap reference source, which produces a constant voltage regardless of the supply voltage or temperature conditions. The amplifier then amplifies the bandgap voltage to the desired output voltage.

The ADR02AR-REEL is well-suited for battery-powered applications because of its low power consumption. Due to its low temperature coefficient, the ADR02AR-REEL can provide a predictable reference voltage over varying temperature conditions, which is necessary in medical applications where temperature compensation is crucial.

The ADR02AR-REEL is also used for analog-to-digital converters, reference voltage generators, and level detectors. In analog-to-digital converters, the precision reference provides a stable reference voltage to measure the input signal, which can very accurately relate the digital values to the analog input. The ADR02AR-REEL can also be used as a reference voltage generator to generate reference voltages that can be used for analog circuits such as amplifiers, comparators, and references for other circuits in a system. Lastly, the ADR02AR-REEL can be used as a level detector to detect specific voltage levels in a system, such as when the input voltage goes above or below a certain threshold.

The ADR02AR-REEL is designed to operate with a supply voltage of between 2.5V to 18V, and has an output voltage of between 0.6V to 14V. It has a temperature coefficient of 0.1 ppm/°C, typical, and a temperature stability of 0.2 ppm/°C, typical. It has a wide range of stable and accurate operating current levels, from 8μA to 200μA, depending on the output voltage. It also has a fast transient recovery time of less than 10μs.

The ADR02AR-REEL is an ideal choice for applications requiring a high level of accuracy in an extremely small package. Its low power consumption, low temperature coefficient, and wide output voltage range make it an ideal choice for use in battery-powered applications, as well as in portable and miniaturized devices. Additionally, its remarkable temperature stability provides a predictable reference voltage over varying temperature conditions.
