AD8402ARUZ100-REELThe AD8402ARUZ100-REEL is a Digital Potentiometer designed for precise control of voltages and other signal values in a range of applications. It is a 2-wire, 10-bit digital-to-analog converter with a superior 12-bit performance and a wide range of features and performance. The main features include low power linear operation, an I²C/SPI serial interface, ultra-low active current, low temperature drift and low offset and gain errors. The AD8402ARUZ100-REEL can be used in a range of applications from telecommunications to industrial and medical equipment.Most digital potentiometers are used in applications that require accurate analog control of a signal’s voltage, resistance, capacitance or a wide range of other properties. They are often used to control power supplies and process control systems, regulate the analog signals for the logic circuitry.The AD8402ARUZ100-REEL is a low power linear 2-wire, 10-bit digital-to-analog converter. The AD8402ARUZ100-REEL has three power connectors, one for the Vcc power supply, one for the circuit ground, and one for the negative voltage supply. The Vcc power supply provides the supply voltage for the device, while the circuit ground is used as the reference point for the device’s signals.The AD8402ARUZ100-REEL features a serial I²C/SPI interface, which provides the means of communication between the device and a microcontroller or microprocessor. The I²C/SPI interface is a two-wire interface, with the Serial Data Line (SDA) used to transmit data and the Serial Clock Line (SCL) used to receive data bit-by-bit. The I²C/SPI protocol supports 7-bit or 10-bit addressing, as well as single-byte or multi-byte operation, giving the user great flexibility in programming the device. It also supports polling mode, which makes it possible to send commands without waiting for a response from the device.The AD8402ARUZ100-REEL can operate with a power supply voltage of 1.8V to 5V, and the minimum supply voltage for the I²C/SPI interface is typically 2.14 V. For a typical application, the passive load resistance range is 6kΩ to 61kΩ.The AD8402ARUZ100-REEL has an impressive 12-bit performance with a low-temperature drift and a low-offset and gain errors. It also features an ultra-low active current that guarantees a low power system design, which is very useful in mobile applications.The AD8402ARUZ100-REEL is an ideal choice for many applications such as automotive systems, power supplies, telecoms and medical equipment. Its flexibility and wide range of features make it a great choice for many design requirements. Its 10-bit and 12-bit performance, low power linear operation and ultra-low active current make it a great solution for reliable and accurate digital control of analog signals and voltage.
