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)

Cute, Smells like Chemicals
Color: Rose Gold #01, Size: 1 Fl Oz (Pack of 1), Color: Rose Gold #01, Size: 1 Fl Oz (Pack of 1)
Looks great but transfers easily. I liked the shade and how the glitter was visible but not distracting. I wasn’t fond of how it smelled but I covered the scent with my sunscreen and I didn’t notice afterwards. Smells like a chemical like scent but it was worth the value I paid for. Good as a highlighter, to add a touch of glow to the face. You can’t see it under foundation but it’s cute on the cheek bones to give a make up less look on a sunny day. The brush is also good quality.

Quick glow up
Color: Glistening Bronze #03, Size: 1 Fl Oz (Pack of 1)
This is a great bronzing shimmer for a little added glow before walking out the door! It's very lightweight and goes on very smooth with brush. I ended up buying and using a larger kabuki brush to brush on faster but the brush it comes with works ok as well. It's the perfect amount of bronze and shimmer.. not glittery or over the top and doesn't have a smell. Doesn't transfer on clothes but I always let it dry a few minutes before putting on clothes.

Beautiful Shimmer
Color: Rose Gold #01, Size: 1 Fl Oz (Pack of 1)
This worked well for a wedding. I thought it would be a little more bronzier but I loved the sparkle. It is my first time using a body shimmer though, so it did what I bought it for and next time just need to self tan prior!

Lovely
Color: Silver White - 02, Color: Silver White - 02
This is the best body glitter I have ever owned. I have a spray one and it is not as shiny as this one. This one has a very good appearance. It literally is shining so bright without the lights being off. This is one drop on my hand that I spread around, it does go on as a liquid and then it dries up and soak in your skin . From the bottle It has a very fresh scent like a very, very light scent, but when you put on your skin, it doesn’t smell like anything so you can still put on your regular perfume without worrying about mixing fragrances. It’s a good decent size especially considering I only did one drop and I get so much glitter!
