GENERAL DESCRIPTION

The Universal Sensors and Transducers Interface (USTI-EXT) is a fully digital CMOS integrated circuit based on novel patented methods for frequency, period, its ratio, duty-cycle and phase-shift measurements. This IC has similar metrological performance as Excelera’s UFDC-1M-16 and same functionalities as the USTI IC but can work in extended operation temperature range from - 55 ºC to +150 ºC.

FEATURES

• 29 measuring modes and one generator mode
• 2 channels for frequency and period measurements
• Frequency (time)-to-digital conversion for many types of sensors and transducers
• Interfacing for resistive (including platinum (Pt), cuprum (Cu) resistors and thermistors (Ni)), capacitive sensing elements and resistive bridges
• Frequency range from 1 Hz up to 7.5 MHz without prescaling and 120 MHz with prescaling;
• Programmable accuracy (relative error) for frequency (period) conversion from 1 % to 0.0005%
• Relative quantization error is constant in all specified frequency range
• Non-redundant conversion time
• Scalable resolution
• Internal reference clock 16 MHz @ 16 MHz quartz oscillator
• Quartz-accurate automated calibration
• 3-wire serial interface (SPI compatible)
• 2-wire interface (I2C compatible)
• RS232/485 serial interface
• Master and slave communication modes
• Frequency generator mode 8 MHz with quartz crystal stability
• Operating temperature range -55 ºC to +150 ºC
