HOME DESIGN SERVICE OTHER PRODUCTS CONTACT Avanti Single Chip Quartz Transducer Counter. The Avanti AVA-07 Quartz Transducer Counter provides a simple solution for converting a traditional frequency output transducer into a digital transducer. It measures pressure and temperature frequencies and returns the results through a Quartzdyne compatible I2C interface. The update rate is 91ms. The gate time is a multiple of 91ms, up to a maximum of 2.8s. The gate time can be configured to be fixed or self adjusting according to the polling rate (MODE link). The counter chip operates from a supply voltage between 2.7V and 5.5V. Current consumption at room temperature is 2.85mA @ 5V or 2.45mA @ 3V. Package is QFP-44. Temperature rating is 165°C (>6 months). A Demo Board measuring 2.75" x 0.7" (69.85mm x 17.78mm) is also available. The demo board contains a counter chip in a QFP-44 package plus a serial EEPROM for holding calibration coefficients. Biasing circuitry is also included, accepting AC or DC coupled transducer signals. There are pads provided for the I2C address links and the MODE link, plus test pads for monitoring the operation with an oscilloscope. The PCB material is standard FR4. Calibration coefficients in traditional CRF/CRT format can be converted into digital HEX format with the CFFconv software utility available for download from HERE. Model-No: AVA-07 (Programmed counter chip, QFP-44 package) Price: £95.- + VAT. Model-No: AVA-07-DEMO (Demo board with counter chip and EEPROM) Price: £185.- + VAT.
