| NTE1866 Integrated Circuit 5-Point LED VU Scale Bar Level Meter Driver Description: The NTE1866 is a monolithic integrated circuit in a 9-Lead SIP type package designed for use as an LED level meter driver for radio cassette recorders and other audio products. Features; D Rectifying amplifiers are used to allow operation by AC or DC input. D The wide display range covers -13dB to +17dB, enabling the display of even signals with wide dynamic range. D The drive current for the LEDs is regulated, eliminating LED current variations with supply voltage variations. D The reference voltage is built in to eliminate output display variations with variations of supply voltage. D Wide supply voltage range (3.5V to 16V) enables a wide range of applications. Applications: D VU meters D Signal meters D Other display devices Absolute Maximum Ratings: (TA = +25C unless otherwise specified) Power Supply Voltage, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 18V Power Dissipation, PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 800mW Derate Above 25C . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6.4mW/C Junction Temperature, TJ . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +150C Operating Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -25 to +70C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -55 to +125C Electrical Characteristics: (TA = +25C, VCC = 12V, f = 1kHz unless otherwise specified) Parameter Power Supply Voltage Quiescent Current Display Range Range 1 Range 2 Range 3 Range 4 Range 5 Input Voltage LED Current Input Current Symbol VCC IQ VC1 VC2 VC3 VC4 VC5 VIN ILED IIN Pin Connection Diagram (Front View) Test Conditions Min 5.5 - -16 -9 - +7 +13 21 11.0 - Typ 12.0 7 -13 -7 0 +10 +17 47 15.0 0.3 Max 16.0 12 -9 -4 - +12 +19 62 18.5 1.0 Unit V mA dB dB dB dB dB mVrms mA A 9 VCC 8 Input 7 Amp Output 6 D5 5 GND 4 D4 3 D31 2 D2 1 D1 .870 (22.0) .110 (2.8) .235 (6.0) 1 9 .195 (5.0) .100 (2.54) .800 (20.32) .012 (0.30) |
