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

Hope the instructions could be clearer
Size: 60 Count (Pack of 1)
365 By Whole Foods Market, Milk Thistle, 60 Count (60 Count (Pack of 1))
The supplement come with capsules. The isnstruction is somehow vague. It says Take a capsule, 1-3 times per day. It does not mention before drink, after drink or during drink. I tried before drink and did not feel much better lol. Probably gonna try a few more times and update this review later.

Affordable fiber supplement!
Size: 84 Count (Pack of 1)
For starters, Amazon is one of the few places that sells these fiber tablets, so I was pleased that they were affordable. I prefer the tablets over the powder because it’s just easier for me to use. Three tablets and you’re good to go for the day. The fiber supplement works well compared to others I have tried. It’s very gentle on your stomach. Worth it!
