Data Acquisition - Digital Potentiometers The AS1500 application field is defined as digital potentiometers, which are compact semiconductor slices engineered to produce a wide range of resistive values across their length. They feature an internal structure of a series of precisely calibrated resistive elements, which helps in providing a broad range of static values for circuit tuning, and for distributing power amongst a variety of devices. They are used for applications such as potentiometric feedback control, dynamic gain adjustment, and active filter circuitry.As for the working principle of the AS1500, when an external voltage is applied to one end of the potentiometer, a certain amount of current passes through the respective resistive elements. This current be used to control the current flowing through the terminals of the potentiometer. The current regulation is achieved by adjusting the resistance of the resistive elements as per the external voltage applied across the terminals. The dynamic gain of the potentiometer can be adjusted through changing the number of elements in the device.An AS1500 digital potentiometer, in particular, comes with an on-device tuning capability and an open-source programming interface, which together offer great flexibility in terms of setting up and configuring the device. The on-device tuning component allows users to control the resistive elements of the potentiometer with the use of an external voltage source. This is done by manually adjusting the Potentiometer’s resistance range, or by setting the target gain for the device.The programming interface component allows users to configure the device with certain parameters such as the gain range limit, the input voltage range and the digital/analog response time. Moreover, the voltage range of the AS1500 can be extended through external precision voltage sources, or a combination of a digital-to-analog converter and a low-noise operational amplifier.The AS1500 offers a wide selection of potentiometers for digital and analog applications, including High-Frequency (HF), Low-Power (LP), Low-Drift (LD) and High-Gain (HG) types. The device is equipped with a wide range of settings and features in order to provide a robust and reliable performance in various types of applications, such as temperature monitoring systems, door access control, smart meters, or in cellular and RF communication systems. The AS1500 has a wide input voltage range of 0.2V to 5V, with a resolution of 0.001V and a frequency range of 13kHz to 600kHz. It also has an adjustable power consumption of 0.4 mW/uA to 15 mW/uA, and a low-noise voltage output of 0.3 μV (Max.).The AS1500 is capable of withstanding harsh environmental conditions, and its advanced energy-saving design and efficient operation makes it the ideal choice for power-sensitive and low-power applications. Additionally, it offers a low temperature coefficient and high stability, which makes it suitable for use in temperature monitoring and critical regulation applications.The AS1500 is an advanced, high-performance analog to digital and digital to analog device.
