Product Overview

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)
