It has a wide range of applications and is available in various resistance ranges and temperature grades. This digital potentiometer is available in both TO-263 and TO-265 packages. The ISL22424WFR16Z-TK has two independent digital potentiometers that can be used in pairs to control separate parts of an electronic circuit. This is ideal for applications where an adjustable resistance must be adjusted without the introduction of other components such as a resistor.

The ISL22424WFR16Z-TK is a low-power device, using a low voltage supply of 3V or 4.5V. It utilizes a CMOS process for high speed operation and low power dissipation. The operating temperature range is -40°C to +125°C for reliable operation in harsh, high temperature environments. The device has a low temperature drift, ±0.2% per °C over the complete temperature range. The five-bit code read from the device provides an indication of the resistance. This digital potentiometer is designed with a ‘no-power’ enable feature, the output will remain constant with no power applied.

The main application fields of the ISL22424WFR16Z-TK are in the high temperature digital systems. It can be used in the motion control, heat and ventilation systems, robotics, medical devices, automated test equipment and automotive sensors. This digital potentiometer also has its application in protecting motor drives and other motor control circuits. It can accurately adjust the resistance of the motor control circuit, creating appropriate power and torque control.

In terms of working principle, the ISL22424WFR16Z-TK operates by adjusting the resistance of the potentiometers by changing its input signal. The signal enters the device from a digital-to-analog converter and is sent to the five-bit pins. The pin-configurable required resistance can then be set. The resistance of the potentiometers is proportional to the data provided from the digital-to-analog converter. When the data to the five-bit pins is changed, the resistance of the potentiometer is adjusted accordingly. The current transmitted to the output is determined by the resistance of the potentiometers.

The ISL22424WFR16Z-TK is a reliable and highly accurate digital potentiometer ideal for use in high temperature digital systems. It is available in a variety of resistance ranges and temperature grades. It has two independent digital potentiometers that can be used in pairs to control separate parts of an electronic circuit, as well as a low power, low voltage supply requirement, wide operating temperature range and low temperature drift. With its high temperature operation and adjustable resistance, the ISL22424WFR16Z-TK is the perfect solution for various high temperature digital systems.
