ISL23445TFRZ-T7A Overview
There is a QFN package containing it.Volatile is the point at which this pentometer starts to be stored.There are embedded 4 circuits in this digital potentiometer.To protect this pentometer from overcurrent, there are 256 taps.Pentometer consists of 256 positions.In this case, the flow can be limited by 100kOhm.A potentiometer conducts when its supply voltage is 3.3V.It is best to have the maximum setting 125°C in order to ensure a stable operation of the digital resistor.The system requires a minimum operating temperature of -40°C to maintain reliability.There is a maximum voltage limit of 5.5V for the supply.A electronic potentiometer minimum supply voltage of 1.7V can be used.
