The CAP1298-1-A4-TR is a 8-channel Capacitive Touch Sensor which incorporates RightTouch® technology. It contains eight (8) individual capacitive touch sensor inputs with programmable sensitivity for use in touch sensor applications. Each sensor input is calibrated to compensate for system parasitic capacitance and automatically recalibrated to compensate for gradual environmental changes. The CAP1298 includes multiple pattern touch recognition that allows the user to select a specific set of buttons to be touched simultaneously. If this pattern is detected, a status bit is set and an interrupt is generated. The CAP1298 has active and standby states, each with its own sensor input configuration controls. Power consumption in the Standby and Combo states is dependent on the number of sensor inputs enabled as well as averaging, sampling time and cycle time. Deep sleep is the lowest power state available, drawing 5µA (typical) of current.
- Programmable sensitivity
- Automatic recalibration
- Calibrates for parasitic capacitance
- Proximity detection
- Isolates the proximity antenna from attenuation
- Reduces system noise sensitivity effects on inputs
- Power button support
- Press and hold feature for volume-like applications
- Analogue filtering for system noise sources
- RF detection and avoidance filters
- Low power operation - 50µA Quiescent current in Standby
- Samples one or more channels in standby
- SMBus/I²C Compliant communication interface
- 8kV ESD rating on all pins (HBM)

Cleans without any harsh fragrance or residue
Scent: Fragrance Free, Size: 12 Fl Oz (Pack of 1)
I got tired of other overly-scented hand soaps and decided to give this a try. It works well for a quick wash after using the toilet and when you're hands are really dirty. It rinses off easily and quickly. While it's unscented, it does have a smell - it's hard to describe, sort of like a bleach-clean scent but, it definitely does NOT smell like bleach. It just smells "clean."
Since it's in the bathroom, it also gets used to clean up some other adult things. Since it isn't scented and doesn't leave any residue it's perfect for things that are in close contact with sensitive areas.

Must Use FOAMING SOAP BOTTLE for this soap & you will Love it!
Scent: Fragrance Free, Size: 64 Fl Oz (Pack of 1)
I have been using this soap refill for years and love it. I also use the scented versions when this is out of stock and they are not very strong scent. But if you prefer no fragrance, then this is a great soap. Many reviewers are complaining it is watery and thin. YES, IT IS. It is SUPPOSED to be. If you don't know how foaming soap works, you do need a couple pumps of foaming soap but you are using a fraction of the amount of soap you would use (aka WASTE) with standard soap. Have you ever seen your kid pump soap in the bathroom? Not once, or twice, but three or four times? Well, they can do that with this soap and not waste it because it's half air in each pump. It's SUPPOSED to be for foaming hand soap. Don't get fooled by your costly regular or foaming soap. Buy this and have clean hands and SAVE money! My family has very sensitive skin and nobody gets rough, red hands from this soap. No problems.

UPDATE ON REVIEW (August 2020): I recently just ordered this item and it was delivered with new packaging. I thought it was the same product, but it seems to have additional ingredients now including alcohol. Hm. Need to look closer into this and will update when figure out what has changed.
UPDATE ON INGREDIENTS (October 2020): The new formula is now showing the ingredients. It has changed. A lot. One ingredient that was removed is PHENOXYETHANOL which is GREAT they removed that! However, if they only removed that, then this would be an amazingly safe hand soap (by EWG standards it would be golden). However, it is a completely different soap with a completely different list of ingredients. I will wait until the EWG rates these ingredients before continuing to purchase this. As other reviewers have noted, it does now have "fragrance" in the ingredients - and misleadingly states "(natural)" next to the word fragrance, which means absolutely nothing in terms of what is allowed and what is not. Do your research on what the word "fragrance" means on labels and what could possibly be in your product under that ingredient. In addition it now does have alcohol in it, which some may like, however I don't think soap needs it. If you are washing, you don't need to sanitize anything. It's overkill ingredient - not needed and dries your hands out.

Cruelty free and works well!
Scent: Fragrance Free, Size: 12 Fl Oz (Pack of 1)
This soap lasts a long time. One bottle lasts one person roughly 3 weeks to a month, depending on frequency of hand washing in a day. It has a slight smell if you get near it that to me smells like a fresh clean smell. It is cruelty free and when I researched the brand, not tested on animals. It also seems like it is made out of healthy ingredients. Overall I will keep buying it.
