The DS1803E-100+T&R device is a digital potentiometer (commonly known as a digipot) used for data acquisition applications. The device has a high resolution of 100 ohms and is designed to provide an accurate and repeatable adjustment of electrical characteristics in a wide range of systems. It is best suited for applications in power control and metering systems, digital sensor systems, communication systems, digital audio systems, automotive systems, consumer electronics, and any application requiring precise digital control.

The DS1803E-100+T&R is a unidirectional, non-volatile, digital potentiometer that offers a temperature compensated, 100 ohm resistance setting range. The solid-state construction of the device makes it well suited for use in applications impacted by temperature, humidity, and vibration.

The device features Non-Volatile Memory (NVM) that retains the adjusted resistance value after power is removed from the system. This allows for setup and adjustment in the lab, before and after shipment to customers, and in the field when needed. Furthermore, it is self-contained and requires no external adjustments.

The DS1803E-100+T&R has two Wiper terminals (W&P) that are connected together by the 100 Ohm sliding potentiometer elements. One of the wiper terminals is provided as an adjustable resistance and the other is provided as a ground reference terminal. The wiper terminals can be used to control the resistance between them, which can be used to adjust the output voltage or current.

The device also has two end terminal pins (A&B) that can be adjusted to change the total resistance between them. The two end terminals are connected to two external resistors and can be used to increase or decrease the total resistance of the device.

The DS1803E-100+T&R can be programmed to have various different output resistance characteristics. These characteristics include a linear, exponential, or logarithmic sensitivity profile. The logarithmic profile is most widely used for applications where the sensitivity of the performance is important.

The device can be used for data acquisition in a wide range of systems. It can be used to adjust the voltage, current, and power dissipation of the system. It can also be used to adjust the frequency, impedance, and power requirements of the system. Furthermore, it can be used to reduce the noise and crosstalk in communications systems.

In addition to data acquisition, the DS1803E-100+T&R can also be used for calibration and adjustment of digital sensors and systems. It can be used to set the zero and span points, to adjust the sensitivity of the system, and to adjust the output levels of the system.

The DS1803E-100+T&R is a versatile and reliable device, making it an excellent choice for high precision data acquisition and calibration applications. With its temperature compensated resistance range, Non-Volatile Memory, programmable gain and resistance curves, and adjustable end terminals, the device is ideal for applications that require precise control and repeatable adjustments.
