PMIC – Voltage Reference

Voltage references are circuit components that provide the basis of a voltage standard to be used by the circuit. They are typically used to provide a constant voltage to circuits that do not require a large amount of current. One such component is the AD589KH.The AD589KH voltage reference is a negative voltage reference device in an 8-pin, surface-mount package with internal reverse polarity protection. It is an ideal component for use in automotive, battery operated systems and for use in noisy environments.The AD589KH reference design operates from a single 9V DC supply and provides a voltage at a temperature coefficient of only 10µV/°C. This type of device is ideal for high resolution and very accurate signal conditioning from ADC and DAC devices in automotive applications and industrial procedures.The AD589KH voltage reference design uses an internal chopper-stabilized architecture. This type of design provides superior accuracy over long-term periods as well as allowing very low-noise operation in noisy environments. This helps eliminate the effects of power supply noise and other interfering signals, which can affect the accuracy of the signal and the performance of the other drivers in the circuit.The AD589KH reference design includes an internal buffer amplifier for driving low-load capacitive loads which allows for high-resolution operation up to 250kHz. The very low noise performance of this type of voltage reference makes it suitable for applications such as audio (A/D and D/A conversion), power management, temperature and humidity control and data acquisition circuits.The AD589KH voltage reference design also features low total harmonic distortion (THD) and low transient response times. The THD enables the device to be used in applications where only clean signals are required, such as audio and video processing. The transient response time further helps to reduce noise and reduce the amount of interference in the circuit.The AD589KH voltage reference design is also highly immune to power supply noise and is rated for wide temperature range of −40 to +85°C. This ensures a robust and reliable design regardless of the application or environment.In conclusion, the AD589KH voltage reference is a versatile device with a wide range of applications, including automotive, data acquisition, power management, and temperature and humidity control. It features an internal reverse polarity protection, low-noise performance, low THD, and low transient response times, making it suitable for use in a variety of demanding applications.
