ADR510ARTZ-R2 is an ultra-precise voltage reference PMIC from Analog Devices. It is widely used in a variety of applications due to its low temperature drift, wide input voltage range, low output noise, and small board area. The technology is particularly ideal for battery-powered applications due to its low dropout voltage capability and its ability to guarantee a precision output voltage accuracy over its full output load range.

ADR510ARTZ-R2 can be used in applications such as data acquisition systems, DACs, analog-to-digital converters, high precision oscilloscopes, sensors, and motor control systems. The output voltage can be set to a precise value set by an external reference pin. By combining the device with external resistors or capacitors, voltage modifications can be made to produce complex waveforms. It also features a shutdown pin and an enable/disable pin that allows the user to control the device power use. Furthermore, ADR510ARTZ-R2 offers a unique feature of tracking two internal band gaps to produce it\'s extremely stable output voltage.

ADR510ARTZ-R2 uses a special circuit system to achieve ultra reliable voltage reference applications. The circuit contains two temperature-compensated band gaps fixed between two reference points, and a pulse-width modulated (PWM) transistor that adjusts the output voltage. The internal band gaps\' temperature coefficient is much lower than the temperature coefficient of the external reference, which is used to set the reference voltage. The bandgap voltage reference is constantly monitored by the error amplifier, which modulates the PWM transistor’s gate source following the reference voltage set.

The internal resistors provide parameter variation, ensuring that the reference voltage is within a few hundred millivolts of the chosen voltage. Through controlling the duty cycle, the pulse-width modulated transistor is also capable of fine adjustment of the reference voltage as it can be adjusted by hundredths of a volt in fine increments. The result is a steady, accurate, temperature-compensated voltage reference that is broadly applicable in many applications.

ADR510ARTZ-R2 is a multi-function voltage reference PMIC from Analog Devices that is ideal for a wide range of applications.
