PMIC - Voltage Reference technology is at the forefront of electronic engineering, power management and voltage regulation. ADR121BUJZ-REEL7 is a versatile, low-power device with a wide range of features and functions that help simplify design and reduce cost for the high-end electronics system OEMs. It utilizes precision temperature-compensated Voltage References that maintain their stability and accuracy even in high-temperature applications. The ADR121BUJZ-REEL7 is ideal for automotive, industrial, communications and consumer applications such as white goods, audio and video devices.

The ADR121BUJZ-REEL7 is a dual-channel precision reference that provides a single low-power output for both positive and negative voltage references. It is designed for use with either an external voltage reference or internal 2.5V reference respectively to provide a stable and accurate output. The device is temperature-compensated and offers minimal temperature drift, providing long-term stability and accuracy. It is capable of operating in wide temperature range of -40 to +125 degree Celsius.

In addition to providing low-power operation, the device is also designed to provide high flexibility and performance. The integrated low-power switching control logic allows the device to be switched off when not in use, thus reducing power consumption. Furthermore, it is capable of providing a wide dynamic range of up to ±3.3V (typical) from a single supply. The output current can be adjusted from 0.1mA to 1.2mA to meets various requirements in different applications. It provides excellent accuracy with tolerance as close as ±1mV @ 25°C. The ADR121BUJZ-REEL7 is designed to support output voltages as low as 1.2V and as high as 6.0V, allowing for a wider range of applications.

The ADR121BUJZ-REEL7 application field is very wide as it used in various operations. It is used as current to voltage reference in power monitoring, battery charger, and automotive applications. The device can also be used in industrial process control, basic instrumentation, audio and video systems, and temperature control systems. Furthermore, it is also employed in medical equipment and motor control applications.

The working principle of the ADR121BUJZ-REEL7 is quite simple. The input voltage is applied across the integrated voltage reference circuit, which maintains its accuracy independent of temperature. The reference output is then compared to the desired setpoint by a comparator, and any changes in the output voltage are amplified to the output voltage by an internal op-amp. The device includes an adjustable current source that is used to set the op-amp gain and thus the desired output voltage. This allows the device to provide a precise and stable power output reference to different voltage needs in the application in a safe and efficient manner.

In conclusion, ADR121BUJZ-REEL7 is a versatile low-power voltage reference that offers precise and stable voltage references for a wide range of applications. It provides excellent accuracy with tolerance close to ±1mV @ 25°C, while providing the precise output voltage adjustment to meet various operating requirements. It is ideally suited for power monitoring, battery charging, automotive, and other industrial, communications and consumer applications such as white goods, audio and video devices.
