The Universal Frequency-to-Digital Converter (UFDC-1) is a universal 2-channel high precision multifunctional signal converter based on novel frequency-time conversion methods. It is suited for any application where frequency and time  parameters have to be measured with very high resolution and programmable accuracy. (from 1 up to 0.001% relative error).

This product can measure frequencies from  0.05 Hz to 7 MHz (112 MHz with pre-scaling), covering almost all frequency-time output sensors range of frequencies and accuracy.

The UFDC-1 is a fully digital CMOS integrated circuit (IC) that can be applied to build a wide variety of digital, smart sensors and intelligent sensor systems. It can be easy included into a digital environment, controlled by an external micro-controller or work independently as a separate measuring unit without an external control. The function selection can be configured in software and hardware.


This IC has RS232, SPI and I2C interfaces.

Price: $16.46 / unit. Volume discounts apply.

Available in 28-lead PDIP, 32-lead TQFP and 32-pad MLF
