Sensors Interfacing ICs are Available in Miniature TQFP Package

 

Toronto (ON), Canada - 21 January 2008: SWP, Inc. has announced that its both UFDC-1 and UFDC-1M-16 sensors interfacing circuits are also available now in 32-lead, Thin (1.0 mm) Plastic Quad Flat Package (TQFP).

 

Both CMOS ICs - two-cannel Universal Frequency-to-Digital Converters can work practically with any sensors form frequency-time signal domain and convert frequency, period, its ratio and difference, duty-cycle, duty-off factor, PWM signal, time interval, pulse width and space, rotation speed, pulse number, phase shift - to - digital. The UFDC-1 and UFDC-1M-16 have high and constant selectable accuracy (programmable from 1 to 0.001 %) in a wide frequency range up to 7.5 MHz (120 MHz), scalable resolution and non-redundant conversion time. Both ICs can work in 16 measuring and one generating modes and have 3 popular serial interfaces: RS-232 (including a master communication mode), I2C and SPI.

 

The main differences between UFDC-1 and UFDC-1M-16 chips are shown below:

 

 

UFDC-1

UFDC-1M-16

Internal reference frequency, MHz 0.5 16
Frequency range 0.05 Hz ... 7.5 (120) MHz 1 Hz ... 7.5 (120) MHz
Conversion time, s 0.0002 ... 0.2 0.00000625 ...0.00625

 

Typical applications are the following:

  • Any frequency, period, duty-cycle, time interval, phase-shift, pulse number output sensors in order to produce a digital output

  • Digital sensors desig

  • Smart (self-adaptive) sensors due to programmable accuracy and non-redundant conversion time - adaptive possibilities of ICs automatically choice the conversion time depending on the given error of measurement and opposite

  • Multifunctional and multiparamters sensors for simultaneous detection various parameters proportional to frequency and duty-cycle carrying the information provided by sensing elements

  • Data acquisition (DAQ) boars and systems for frequency-time parameters

  • Virtual instruments

  • Desktop multifunctional frequency counters

  • Tachometers and tachometric systems

  • Handheld multimeters for frequency-time parameters of electric signals

  • High-end, mid- and low-range ABS

  • High accuracy programmable frequency-time parameters–to–digital converters for different measuring and communication applications

  • Advanced analog-to-digital conversion using a voltage-to-frequency converters for remote sensors
