NTE1510 Integrated Circuit 5Step LED Driver for Linear Scale
Description: The NTE1510 is an integrated circuit in an 8Lead SIP type package designed for use in level meter applications. This device is capable of driving 5 LEDs to create a bartype display. In accordance with the input level, the uppermost LED brightness varies to form a linear indicator, making the NTE1510 ideal for use in signal meters and VU meters. A lowvoltage reference power supply is builtin, so that the only external components required are LEDs, resistors, and capacitors. Features: D BarType Display of Input Level using 5 LEDs D The Uppermost LED Brightness Varies Linearly With Respect to the Input Level Resulting in a HighResolution Display with No Radiation. D BuiltIn Reference Supply D By Changing the External Reference Values, the LED Brightness can be Adjusted D Wide Range of Supply Voltages: VCC = 4V to 18V D High Input Impedance: IIN = 100nA Typ Applications: D Signal Meters D VU Meters D Tuning Meters D General Purpose Display Applications Absolute Maximum Ratings: (TA = +25°C unless otherwise specified) Supply Voltage, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 18V Input Voltage, VIN . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6V Output Breakdown Voltage, BVO . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 18V Output Current (Per Pin), IO . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 15mA Power Dissipation (Note 1), PdF . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 550mW Derate Above 25°C . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5.5mW/°C Operating Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 20° to +75°C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 40° to +125°C Note 1.
