Product Details
__
CAPACITANCE TO ANALOG CONVERTER
**The QT301 charge-transfer (QT) IC is a self-contained Capacitance-to-
Analog-Converter (CAC) capable of detecting femotofarad level changes in capacitance. This part is designed primarily for stand-alone instrumentation applications.**
Primary applications include fluid level sensors, distance sensors, material
detectors, transducer amplifiers for pressure and humidity sensing functions,
and other uses requiring quantified capacitance data.
Unlike other Quantum products, the QT301 does not process its acquired data.
Its only output is raw, unprocessed data in filterable PWM form that can be
translated into an analog voltage by a simple RC network. This allows the
designer to treat the device as a CAC for measurement applications.
● Capacitance to Analog Converter (CAC) IC
