ISL95710WIU10Z-T

The ISL95710WIU10Z-T is a digital potentiometer in a surface-mount TDFN package, which combines both an 8-bit Non-Volatile Memory (NVM) and an 8-bit Digital Wide Range Potentiometer in one single component. This product is aimed for industrial applications that require a programmable multi-turn potentiometer for the adjustment of resistance on a circuit, particularly in applications with limited space.

The ISL95710WIU10Z-T is a part of a series of digital potentiometers with different resistance values and packages. Its wide application field range from portable electronics such as laptop computers, smartphones and tablets, to industrial applications such as pressure measurement and motor control systems as well as automotive electronics. Moreover, it is ideal for use in audio and position control applications.

The ISL95710WIU10Z-T works on that same principle as a mechanical potentiometer. The voltage divider principle is applied to a resistive track with a tapped wiper located at the midpoint. The output value of the divider can be varied by adjusting the position of the wiper on the track. However, the major differentiating aspect of the ISL95710WIU10Z-T is its NVM which stores the wiper position. This makes the design more reliable, simplifies the integration of the digital potentiometer, and eliminates potentiometer parameters drift with age.

The integrated NVM of the ISL95710WIU10Z-T has 8-bit resolution (256 tap positions) and 4 byte storage capacity and is suitable for use in a wide range of voltage references. This part also provides non-volatile and precise wiper resistance adjustment results with a programmable end-to-end resistance of 10 kΩ. With precise wiper control, this digital potentiometer offers temperature stability and an improved wiper resistance accuracy of ±0.08% over any temperature range.

The ISL95710WIU10Z-T is optimized for speed and current consumption, making it a reliable and low-power choice for digital potentiometers applications. It features a fast programming voltage of less than 1.5V and very low in-circuit current consumption of 1.1 μA. In addition, this part is rated for a maximum of +85°C operating temperatures and is AEC-Q100 qualified.

The ISL95710WIU10Z-T supports several industry-standard communication protocols including I2C, SPI and three-wire for ease of integration into a variety of applications. It also features power down and reset blocks that can be used to protect the device under adverse operating conditions.

Overall, the Integrated cmos ISL95710WIU10Z-T digital potentiometer offers a more reliable and precise resistance-adjustment solution compared to mechanical potentiometers. Its wide application range, small size and low power consumption makes it a perfect choice for portable and industrial applications.
