The Universal Sensors and Transducers Interface – USTI-EXT is a multi-signal converter for frequency – time, resistance, capacitance and resistive bridges suitable for harsh environments.
This IC has similar metrological performance as the UFDC-1M-16 and the same functionalities as the USTI IC but can work in extended operation temperature range from – 55 ºC to +150 ºC (AEC-Q100 Grade0).
In comparison with the basic USTI, the USTI-EXT has the reduced external clock frequency 16 MHz, but increased internal reference frequency from 625 kHz to 16 MHz, and as consequence, reduced conversion speed from 6.25 us to 12.5 ms for relative errors from 1 % to 0.0005 % respectively. The IC has also increased baud rate for the RS232 serial interface: up to 76 800. Active supply current does not exceed 12 mA. T
