1 Device Overview
1.1
Features
1
• CapTIvate™ technology – capacitive touch
– Performance
– Fast electrode scanning with four
simultaneous scans
– Support for high-resolution sliders with up to
1024 points
– Proximity sensing
– Reliability
– Increased immunity to power line, RF, and
other environmental noise
– Built-in spread spectrum, automatic tuning,
noise filtering, and debouncing algorithms
– Enables reliable touch solutions with 10-V
RMS common-mode noise, 4-kV electrical
fast transients, and 15-kV electrostatic
discharge, allowing for IEC‑61000-4-6,
IEC‑61000-4-4, and IEC‑61000-4-2
compliance
