USTI to Digital Transducer serial, SPI and I2C Interface

Part Descriptions

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.
