Integrated Circuit
5–Step LED Driver for Linear Scale
Description:
The NTE1510 is an integrated circuit in an 8–Lead SIP type package designed for use in level meter
applications. This device is capable of driving 5 LEDs to create a bar–type 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 low–voltage reference power supply is
built–in, so that the only external components required are LEDs, resistors, and capacitors.
Features:
D Bar–Type Display of Input Level using 5 LEDs
D The Uppermost LED Brightness Varies Linearly With Respect to the Input Level Resulting in a
High–Resolution Display with No Radiation.
D Built–In Reference Supply
D By Changing the External Reference Values, the LED Brightness can be Adjusted
D Wide Range of Supply Voltages: V_CC = 4V to 18V
D High Input Impedance: I_IN = 100nA Typ
Applications:
D Signal Meters
D VU Meters
D Tuning Meters
D General Purpose Display Applications
Absolute Maximum Ratings: (T_A = +25°C unless otherwise specified)
