Add to Cart:

Product Description:

The IR2431 12 Dot Log-Scale LED Display Driver is a log scale driver suitable for driving 12 LED level meters.
With Vref-max and Vref-min given, the reference voltage is 12-divided by the resistance ratio. This is compared with the Vin in each of the comparator circuits to cause the output "High" or "Low" in the AND gate to turn on the corresponding transistor and the LED will glow.
LED current can be set using an external resistor.
22-Pin dual-in-line package.
IC Length and Width: 1.062" X 0.420"
Pin Distance Across IC: 0.390"
In-Line Distance (Pins): 0.100"
Uses a larger 22-pin socket, optional.
