NTE1503 Datasheet | NTE Electronics

Description : The NTE1503 is an integrated circuit in a 9- Lead SIP type package designed for driving 5- LED bar graphs or dot displays so that the LEDs may light logarithmically (d B) for input signal. Brightness of the LEDs can be controlled by using the output current adjustment pin provided. Features : D 5- LED Bar Graph or Dot Display Drive D Logarithmic Response with Respect to Input D Brightness Externally Adjustable D High Output Current, Suitable for Green LED Drive D Lamp ON/OFF Hysteresis, No Flickering by Noise Absolute Maximum Ratings: (TA = +25°C unless otherwise specified) Supply Voltage, VCC - - - - - - - - - - - - 0.5V to +18V Circuit Voltage, V8- 5 - - - - - - - - - - - - 0.5V to +16V Load Current Set Input Voltage, V7- 5 - - - - - - - - - . . . +16V Output Voltage (Note 1), VO - - - - - - - - - . . . - 0.5V to +16V Supply Current, ICC - - - - - - - - - - - - . . . 18m A Load Current Set Input Current, I7 - - - - - - - - - . . . . 4.25m A Output Current, IO - - - - -...
