Data Acquisition - Digital Potentiometers enables electronic circuits to be programmed or adjusted without the need for physical connections. This is an important factor when it comes to digital signal or image acquisition and manipulation. AD8402AR1-REEL is a precision digitally programmable resistor that makes it possible to directly program, adjust and monitor the value of resistance in a circuit.

The AD8402AR1-REEL is a highly reliable device that is built on a low-power low-voltage process. It consists of a non-volatile memory and a combination of several transistors that are programmed together to recreate a varying resistance. In order to program or adjust the resistance of the device, it is required to send out a control signal in accordance with the desired resistance value. The device adapter makes it possible to monitor the output status of the digital potentiometer in order to ensure the desired resistant value is continually applied.

The AD8402AR1-REEL application field can range from auto-gain systems, digital signal processing modules and electronic tuning of an analog filter. It is able to resolve up to ten bits of resolution between binary values and is capable of providing up to 512 steps in resistance. It is also equipped with a low-current sleep mode for even greater energy savings. This mode is particularly useful for applications where battery operation is desired.

In terms of performance, the AD8402AR1-REEL has an excellent temperature coefficient that can maintain its output logic level at high temperature. It also has very low temperature drift and an input-referred linearity that is within 1 LSB at 25°C. What’s more, the device is extremely accurate with a typical resistor accuracy of 0.25%. This makes it ideal for a range of applications such as volume control, automotive air conditioning and pressure control.

As with most digital potentiometers, the AD8402AR1-REEL is also very versatile in terms of its power supply options. It is able to range from a low voltage source of 4V to a high voltage source of 20V. The device also provides a wide range of options for its input signals. This includes 1-channel, single-ended, and dual-ended type configurations.

The AD8402AR1-REEL working principle is simple in that it can be programmed with an appropriate control signal according to the desired resistance. This control signal is then sent to the non-volatile memory of the device and translated into a combination of transistors that together create the desired resistance. The voltage drop across the resistor is then used to measure and monitor the resistance value. The resistor is then held in place until it is readjusted, resulting in a very accurate and reliable system that can also be easily monitored.

In summary, AD8402AR1-REEL is a precision digitally-programmable resistor that is built on a low-power low-voltage process. Its application field range from auto-gain systems, digital signal processing modules and electronic tuning of an analog filter. It has an excellent temperature coefficient, very low temperature drift and input-referred linearity that is typically within 1 LSB at 25°C. Its working principle is based on a control signal that is translated into a combination of transistors that together create the desired resistance. This makes it an ideal choice for applications such as volume control, automotive air conditioning and pressure control.
