MAXIM INTEGRATED PRODUCTS MAX5438EUB+ Volatile Digital Potentiometer, Low Drift, 100 kohm, Single, SPI, Linear, ± 25%, 10 VThe MAX5438EUB+ is a 15V low drift digital potentiometer in 10 pin MAX package. This device is a single 128 position high voltage digital potentiometer which performs the same function as mechanical potentiometer but replace the mechanics with a simple digital interface. The resistor string uses its own analogue supplies (VDD and VSS) that require VDD VSS to be greater than 9V and less than 31. 5V which allows for greater flexibility in voltage ranges
The MAX5438EUB+ is a ±15V low drift digital potentiometer in 10 pin µMAX package. This device is a single 128 position high voltage digital potentiometer which performs the same function as mechanical potentiometer but replace the mechanics with a simple digital interface. The resistor string uses its own analogue supplies (VDD and VSS) that require VDD - VSS to be greater than 9V and less than 31.5V which allows for greater flexibility in voltage ranges that can be used with the device.
- Supply voltage range is 10V to 30V (single supply operation)
- 28V to -10V single negative supply operation
- ±5V to ±15V dual supply operation
- Operating temperature range from -40°C to 85°C
- Power-on reset, wiper goes to midscale (position 64)
- Ratiometric temperature coefficient of 5ppm/°C
- End to end resistance is 100Kohm at ±25% tolerance and temperature coefficient is 35ppm/°C
- Glitchless switching between resistor taps
- 3-wire SPI/QSPI/MICROWIRE compatible serial interface

Direct replacement for my J Deere GT225
Fit my John Deere GT225 as a direct replacement. It did need to be re-gapped before installation. I think the price was fair for two spark plugs, now I have a spare.

Fits well, sane quality as the oem installed
Works really well, it fits and matches the original spark plugs and very easy to install. Very affordable! It starts right up , quality is very good and didn't have to adjust the gap on spark plugs!

Fresh Spark Plug for the Mowing Season
Just what my push mower needed! Very compatible with my Craftsman M220 push mower. It was the right replacement part and workings just like the original brand B&S plug. Gap was correct right out of the box as my push mower fired right up first pull. Would recommend for anybody with a Craftsman M220.
