PCA9691BS/1,118 Overview
Package 16-VQFN Exposed Pad includes it.The Tape & Reel (TR) package contains this data acquisition unit.Normal operation should be performed with the working temperature set to -40°C~85°C.There is a possibility that you will be repaid what you paid from the outstanding ADC, DAC.This part will save even more space if it is mounted through Surface Mount.As this unit is designed, if your meter does not read a voltage of 2.5V~5.5V, the circuit should be re-built.Total, there are 16 terminations that have been made.In order to access high performance for a wide range of applications, we have included the 1 functions here.Due to the deployment of 4 channels, this unit is able to perform complex tasks very efficiently.In case you're looking for parts with similar specifications, try searching "PCA9691".The voltage to be applied to this data acquisition unit is 5V.In terms of pin count, it has a total of 16 pins.A power supply of at least 0 is needed for it to function.No voltage is allowed to exceed 5.5V.
