64-Position, One-Time-Programmable (OTP) Digital Potentiometer
Along with its unique OTP feature, the AD5273 lends itself well to general digital potentiometer applications due to its effective resolution, array resistance options, small footprint, and low cost.
An AD5273 evaluation kit and software are available. The kit includes the connector and cable that can be converted for factory programming applications.
For applications that require dynamic adjustment of resistance settings with nonvolatile EEMEM, refer to the AD5231, AD5232, AD5233, and AD5235 family, and the AD5251, AD5252, AD5254, AD5258, and AD5259 family of nonvolatile memory digital potentiometers.
1 OTP allows unlimited adjustments before permanent setting.
2 Analog Devices cannot guarantee the software to be 100% compatible to all systems due to the wide variation in computer configurations.
3 Applies to 1 kΩ parts only.
4 The terms digital potentiometer, VR, and RDAC are used interchangeably.
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
The AD5273 supports single-supply 2.7 V to 5.5 V operation, making the device suited for battery-powered applications and many other applications with superior low temperature coefficient performance.
The on-board socket allows the user to easily replace the device for reprogramming of the OTP memory.
In addition, the AD5273 uses a versatile I2C serial interface that operates in fast mode, allowing speeds of up to 400 kHz.
The EVAL-MB-LV-SDZ can operate in single-supply mode and incorporates an internal power supply from the USB.
Complete specifications for the AD5273 part can be found in the AD5273 data sheet.
