Data Acquisition – Digital Potentiometers encompass a range of instruments intended to provide a digital-to-analog interface for data processing. The AD5110BCPZ80-500R7 is a popular Digital Potentiometer specifically designed for automotive and industrial applications. This device is a three-terminal adjustable precision potentiometer with a lenient resistance range from 500 to 1,000,000 Ohms and a standard logic control interface.

The device offers a variety of features and specifications which make it a solid choice for automotive, industrial and even some consumer markets. It features a single-pole and three-throw switch, a 5-bit wired binary weighting which enables the device to operate more efficiently and accurately, a positive and negative operating supply voltage of 4.75V to 5.25V, a resistance range of 500 to 1,000,000 ohms, and a temperature coefficient of 0.01%/°C, which ensures a stable output over a wide temperature range. Additionally, it offers an open-drain digital pin to enable a simple 1-wire or 2-wire interface, allowing the user to control the device with a low logic voltage.

The AD5110BCPZ80-500R7 works by taking an input signal from a ADC (Analog-to-Digital Converter) and converting it into a analog adjustment of the wiper on the digital potentiometer element. All adjustments are done by the device’s digital control logic and the external ADC data. The device performs all calculations and then sends back the control signal to control the external device.

The device’s internal logic is a monostable multivibrator and a NAND gate. The monostable multivibrator stores reset, set, and data signals in a flip-flop and compares the bits of the ADC data with the Digital Potentiometer wiper setting. When a match is found, a control signal is passed to the NAND gate which then controls the external device.

The AD5110BCPZ80-500R7 offers enhanced features, stability, and flexibility. Its single-pole and three-throw switch, allows for increased linearity, accuracy, and stability for demanding automotive and industrial applications. Additionally, the device’s integrated 5-bit wired binary weighting enables the user to access four additional resistance values from the 100 to 1,000,000 Ohm range. This ensures that the resistance value can be controlled and manipulated with great precision.

The AD5110BCPZ80-500R7 is an advanced Digital Potentiometer ideal for automotive and industrial applications with a tight tolerance for resistance values. Its temperature coefficient ensures that the device is stable over a wide temperature range and its integrated open-drain digital pin enables a simple 1-wire or 2-wire interface. With its increased accuracy, flexibility, and stability, the device is a prime choice for data acquisition and digital signal processing.
