ADR5043AKSZ-R2 Application Field and Working Principle

The ADR5043AKSZ-R2 from Analog Devices is an integrated voltage reference in a SOIC-8 package. It is suitable for applications where shunt regulation and low noise are required. This device is classified as a PMIC (power management integrated circuit) - Voltage Reference.

The ADR5043AKSZ-R2 is a low-dropout, low-noise, ultra-low current and high-accuracy adjustable voltage reference. It provides a 5V ±2% reference voltage with an output voltage range from +1.5V to +5.5V. The device is stable over varying temperatures and supply voltages, and it is ideal for use in low voltage systems like cell phones and other battery-powered devices.

The ADR5043AKSZ-R2 consists of a low-noise reference, two error amplifiers, and two output drivers. The reference voltage is generated by an on-chip bandgap reference and is adjustable using an external resistor divider network. The output voltage is adjustable over the full range using the resistor divider network.

The ADR5043AKSZ-R2 uses the shunt regulation method to control output voltage, which makes it ideal for applications that require a stable and low noise output voltage. Its output voltage is controlled by an internal error amplifier, which measures the output voltage against the defined reference voltage and adjusts the output voltage accordingly. The error amplifier ensures that the output voltage is regulated to the desired voltage level despite varying load conditions and temperature.

The device is also equipped with a low power consumption feature that allows it to maintain a stable output voltage in battery-powered applications. It requires only 4μA of bias current for output regulation, making it ideal for use in low-power or low-noise applications. It is also designed to be used in low voltage systems that require a low drop-out voltage. The device is rated to withstand up to 10V of reverse voltage.

The ADR5043AKSZ-R2 is available in an 8-pin SOIC surface mount package. It has an operating temperature range of -40°C to +85°C, and can operate with either 5V or 3V supplies. It is RoHS compliant and is intended for automotive applications.

The ADR5043AKSZ-R2 is an ideal choice for applications that require a stable, low-noise and adjustable voltage reference. It can be used for shunt regulation in battery-powered and low-voltage systems, providing a reliable and adjustable output voltage. It consumes very low power and is ideal for applications that need low power consumption.
