Smartec UTI Sensor to Digital Transducer,  SOIC

Smartec UTI Sensor to Digital Transducer, SOIC

In Stock
For quantity 10+

The Smartec Universal Transducer Interface (UTI) is a complete analog front end for low frequency measurement applications, based on a period-modulated oscillator. Sensing elements can be directly connected to the UTI without the need for extra electronics. Only a single reference component, of the same kind as the sensor is required. The UTI outputs a microcontroller compatible period-modulated signal. The transducer can measure very accurately capacitance, platinum resistors, thermistors and resistive bridges. To accelerate sensor design with the SMT UTI an evaluation board SMT TOOLKIT is available. Available in different packages UTI-SOIC and UTI-DIL.

* Full sensor solution on a chip
* Sensing elements can be directly connected to the UTI without the need for extra electronics.
* Single supply voltage 2.9V to 5.5V, 2.5mA supply
* Continues auto calibration of offset and gain.
* Typical measurement time 10mS or 100mS
* Capacitive sensors modes: 0 to2pF, 0 to 12pF and <300pF
* Platinum resistors Pt100, Pt1000
* Resistive bridges 250 Ohm to 10kOhm with maximum imbalance ±4% or ±0.25%
* 2,3 or 4 wire measurement modes for resistive measurements
* AC excitation voltage for all sensor elements
* Suppression for interference of 50Hz and 60Hz
* Applications: Capacittive level sensing and distance sensing, position and angle sensing, Wheatstone bridge setup for pressure, force, platinum, NTC...
