KA2903 Overview

The product is packaged in DIP in order to facilitate transportation.Output type of this comparator is OPEN-COLLECTOR .The comparator has 8 terminals.The electrical component in this case belongs to the Comparator family.This comparator is capable of handling a wide range of tasks if it is supplied with a voltage of 5V .The device includes 8 pins.8 pins are available on the comparator.A quiescent current of 2.5mA is observed in this comparator.A Through Hole is provided for mounting it onto a PCB or another board.Normal use of the device should require a nominal supply current of 1mA .An excess of current supply over 1mA could result in malfunction of the comparator.A power supply of 5V is sufficient for the operation of the device.You are allowed to input a maximum current of 250nA into the device.The voltage gain of the part is indicated by 100dB in the voltage formula.There is no recommendation for temperatures higher than 85°C .Temperatures below -40°C are not suitable for the device.Compatibility is defined as 36V when the comparator is operating at its maximum supply voltage.A minimum supply voltage of 2V is allowed for this comparator.The output quality of 2 channels is maintained by cooperating with each other.Comparator electronics is essentially a highly gain-adjustable COMPARATOR amplifier that forms the comparator.Its output current is rated as 16mA .
