Data Acquisition - Digital Potentiometers
Digital potentiometers (also called digital rheostats) are electronic components that are used to adjust the resistance value in a circuit. They work similarly to mechanical potentiometers, except they use microscopic switches instead of a physical contact. A digital potentiometer is a single integrated circuit (IC) with multiple, internally connected resistors. The overall resistance can be adjusted by simply selecting one resistor in the chain.The AD5292BRUZ-20-RL7 is an example of a digital potentiometer IC. This IC is a 16-pin device, with 8 resistors. It has a 10 kΩ resistance range, with a maximum of 20 kΩ. It has a voltage supply voltage range of 1.5V to 6V, and an operating temperature range of -40°C to 85°C. It features nonvolatile memory, which allows it to retain its last set resistance even when power is removed. A common application for this type of IC is to programmatically adjust the resistance in a volume control or other adjustment circuits.The IC works by using a four wire serial interface, typically known as a “SPI” or “TWI” interface. It works similarly to an analog voltage-controlled potentiometer – the output resistance is determined by the control voltage that is applied to the control lines. It can be controlled manually by connecting the control lines to a potentiometer, or electronically by applying an appropriate voltage. The chip has two digital input pins – a “Chip Select” (CS) and “Data In” (DIN) pin. When the CS pin is asserted (low), the chip accepts data from the DIN pin. Each 8 bit byte sent to the chip specifies the relative position of the tap within the resistor chain. The output pins of the chip are a “Data Out” (DO) pin and an “Output High-Z” (OH) pin. The DO pin sends data from the chip to any other device, such as a microcontroller or other device. The OH pin provides the option of putting the output in a high impedance state, which is useful for disconnecting the device from the circuit.The primary benefit of using a digital potentiometer is convenience. It allows the user to easily adjust the resistance value of a circuit without having to manually move a slider or dial. It is also much more reliable than a standard potentiometer, as it is immune to vibration and wear and tear.In summary, the AD5292BRUZ-20-RL7 is a 16-pin digital potentiometer IC with 8 resistors, a 10 kΩ resistance range, a voltage supply voltage range of 1.5V to 6V and an operating temperature range of -40°C to 85°C. It can be used to adjust the resistance in a variety of applications, from volume control circuits to adjustable power supplies. The primary benefit of using a digital potentiometer is that it is more reliable and convenient than a standard potentiometer.The specific data is subject to PDF, and the above content is for reference
