ADR293GRZ is a voltage reference type of PMIC chip. The key feature of this PMIC chip is its excellent temperature coefficient, ensuring precise and stable output voltages. ADR293GRZ was designed to provide an extremely accurate voltage reference source, even in wide range of temperatures, where traditional voltage references may be more inaccurate.

This PMIC chip provides up to 0.02% pre-calibrated initial accuracy, which is higher than most voltage reference products. Besides, it also owns low temperature coefficient, power supply rejection and low noise. This is why the ADR293GRZ is commonly used for high reliability reference systems, such as in medical devices, automotive applications, data acquisition systems and much more.

ADR293GRZ utilizes a bandgap technology principle to generate an excellent temperature coefficient voltage reference. This band gap technology consists of two transistors connected in a specific way, allowing the same output voltage at different temperatures. It essentially eliminates the risk of temperature drift found in traditional voltage references.

This device utilizes a series of resistors, tapped as a voltage divider. The tapped point source current will be biased to the output terminal, to produce the reference voltage. ADR293GRZ also owns a trimmed high-value resistor, which is used to fine-tune and adjust the output voltage. Finally, a bypass capacitor is connected to the output terminal, in order to reduce the power supply noise, while providing good stability to the reference pin.

In summary, ADR293GRZ is a highly stable and accurate voltage reference PMIC chip, which is widely used in medical devices, automotive industries and more. This chip utilizes an advanced bandgap technology, which provides an excellent temperature coefficient voltage reference, with low temperature coefficient, power supply rejection and low noise. On top of that, the chip provides up to 0.02% pre-calibrated initial accuracy, ensuring precise and stable output voltages.
