Quick Detail:
PROGRAMMABLE CAPACITANCE SENSOR IC
Description:
The QT310 is a digital burst mode charge-transfer (QT) sensor designed for touch controls, level sensing and proximity sensing; it includes all hardware and signal processing functions necessary to provide stable sensing under a wide variety of changing conditions. Only one low cost sampling capacitor is required for operation.
A unique aspect of the QT310 is the ability of the designer to‘clone’ a wide range of user-defined setups into the part’s eeprom during development and in production. Cloned setups can dramatically alter the behavior of the part. For production, the parts can be cloned in-circuit or can be procured from Quantum pre-cloned.
Applications:
Single channel digital advanced capacitance sensor IC
Spread spectrum burst modulation for high EMI rejection
Full autocal capability
User programmable via cloning process
Internal eeprom storage of user setups, cal data
Variable drift compensation & recalibration times
BG and OBJ cal modes for learn-by-example
Sync pins for daisy-chaining or noise suppression
Variable gain via Cs capacitor change
Selectable output polarity, high or low
Toggle mode (optional via setups)
Push-pull output
Completely programmable output behavior via cloning process from a PC
HeartBeat™ health indicator (can be disabled)
