PMIC - Voltage Reference

The LM285DRG4-2-5 is a precision voltage reference IC designed to provide a regulated source of DC electricity by using two distinct reference voltages. This technology is most commonly used in applications such as power supply design, power management, and process control. The primary purpose of a voltage reference is to provide an accurate, stable voltage level that can be used as a reference for power supply design, as well as system monitoring and control.

Overview of LM285DRG4-2-5

The LM285DRG4-2-5 is a 4-channel, 12-bit, low-power, single-channel voltage reference that provides two reference voltage outputs. The two reference voltages are 5 VCC (VL/2) and 5.5 VCC (VL/2 + 0.5VCC). It is also capable of providing 2 VCC (VL/2) and 2.5 VCC (VL/2 + 0.5VCC) as well as 3 VCC (VL/2) and 3.5 VCC (VL/2 + 0.5VCC). The device is designed for multiple applications, such as power supply design, power management, process control, display control, and other measurement tasks. The power supply voltage range is from 2.7 V to 4.5 V and the reference voltage output accuracy is 1%. The output voltage range is from 0.1 V to 4.8 V.

Application Field and Working Principle

The LM285DRG4-2-5 is an ideal solution for multiple applications that require an accurate and stable voltage reference as a reference point when working on power supply design, process control, display control, and other measurement tasks. It can be used in applications such as power supply design, power management, medical instrumentation, process control, and other measurement tasks. The integrated temperature compensation feature of the device enables it to maintain its accuracy across a wide range of temperatures.

The LM285DRG4-2-5 consists of four drivers, a voltage reference, and a temperature compensation circuit. The voltage reference is designed using a bandgap reference circuit. This circuit is used to generate an accurate and stable voltage level even when the power supply voltage changes. The temperature compensation circuit was designed to compensate for temperature dependent changes in the references generated by the bandgap reference circuit. This ensures that the output of the LM285DRG4-2-5 remains accurate across a wide temperature range.

The LM285DRG4-2-5 also features an impedance-matching network. This network is used to minimize the parasitic capacitance. The four drivers coupled with the voltage reference and the temperature compensation circuit enable the LM285DRG4-2-5 to provide an accurate, stable output voltage over a wide voltage range. This device is a reliable and cost-effective solution for multiple applications that require an accurate, stable voltage reference.
