Enhanced Features
The AD5235-EP is a dual-channel, nonvolatile memory,digitally controlled potentiometer2 with 1024-step resolution.The device performs the same electronic adjustment function as a mechanical potentiometer with enhanced resolution, solid state reliability, and superior low temperature coefficient performance.The AD5235-EP’s versatile programming via an SPI®-compatible serial interface allows 16 modes of operation and adjustment including scratchpad programming, memory storing and restoring,increment/decrement, ±6 dB/step log taper adjustment, wiper setting readback, and extra EEMEM for user-defined information such as memory data for other components, look-up tables, or system identification information.
In scratchpad programming mode, a specific setting can be programmed directly to the RDAC2 register that sets the resistance between Terminal W and Terminal A, and Terminal W and Terminal B. This setting can be stored into the EEMEM and is restored automatically to the RDAC register during system power-on.
The EEMEM content can be restored dynamically or through external PR strobing, and a WP function protects EEMEM contents.To simplify the programming, the independent or simultaneous linear-step increment or decrement commands can be used to move the RDAC wiper up or down, one step at a time. For logarithmic ±6 dB changes in the wiper setting, the left or right bit shift command can be used to double or halve the RDAC wiper setting.
The AD5235-EP patterned resistance tolerance is stored in the EEMEM. Therefore, in readback mode, the host processor can know the actual end-to-end resistance. The host can execute the appropriate resistance step through a software routine that simplifies open-loop applications as well as precision calibration and tolerance matching applications.
The AD5235-EP is available in a thin, 16-lead TSSOP package.The part is guaranteed to operate over the extended industrial temperature range of −40°C to +125°C.
Full details about this enhanced product, including theory of operation, register details, and applications information, are available in the AD5235 data sheet, which should be consulted in conjunction with this data sheet.
