The Universal Sensors and Transducers Interface ( USTI ) is a fully digital CMOS integrated circuit for use with any sensor or transducer with a frequency, period, duty-cycle, interval, PWM , phase shift or pulse number output. The USTI is perfectly suited to any applications where frequency-time parameters or sensors output signals need to be measured with highest resolution and programmable accuracy. Non-redundant conversion time. The design is based on novel advanced methods for frequency, period, duty-cycle and phase-shift measurements. Available as PDIP, TQFP,MLF and DIE packages.

The USTI covers a wide range of frequencies and accuracies for modern frequency-time domain sensors. In addition, the USTI provides interfacing for resistive (including platinum, cuprum resistors and thermistors), capacitive sensing elements and resistive bridges. The device represents a high-resolution conversion and is designed to support all range of frequency-time domain and digital sensor applications. The USTI offers high performance with flexibility and requires minimum external components.

* 2 channels sensor solution on a chip
* Single supply voltage 4.5V to 5.5V
* Programmable accuracy for frequency conversion 0.0005% to 1%
* Scalable resolution
* Capacitive measurement from 50pF to 100µF
* Platinum and Cuprum (Cu) resistors Pt100, Pt1000
* Resistive bridges 10 Ohm to 10MΩ
* Applications: Physical, chemical and biosensors, smart sensors, virtual instruments, capacitive sensing, frequency measurement

By using this IC it is possible to build a wide variety of digital, smart sensors and intelligent sensor systems. The device represents a high-resolution conversion and designed to support all range of frequency-time domain and digital sensor applications. It offers high performances with flexibility and requires minimum possible number of external components. The USTI can be easy included into digital environment, controlled by an external microcontroller (slave mode) or work independently as a separate measuring unit without an external control (master mode). The function selection can be configured in both software and hardware.
