KA2283

The KA2283 is a kind of monolithic integrated circuit. The device includes 2 channel LED level meter driver designed for use in stereo radio cassette tape recorder and home stereo.  There are some features as follows: (1)suitable for AC level meter driver; (2)comparator level (-8, -6, -4, -2, 0 dB)*2; (3)capable of driving red/green/yellow LEDs; (4)externally adjustable gain of input amp; (5)wide operating supply voltage range (5 V to 14 V); (6)10 dot dual output combinated with KA2281; (7)applicable to 10 dot mono output; (8)high input impedance; (9)minimum number of external parts required.

What comes next is about the absolute maximum ratings of KA2283 (Ta=25): (1)supply voltage, VCC: 18 V; (2)D terminal output current, ID: 30 mA; (3)power dissipation, PD: 600 mW; (4)operating temperature, Topr: -20 to +70; (5)storage temperature, Tstg: -40 to +125.

The following is about the electrical characteristics of KA2283 (Ta=25, VCC=12 V, f=1 kHz, unless otherwise specified): (1)quiescent circuit current, ICC: 4 mA typ at VI=0; (2)D terminal ON voltage, VOL: 1.5 V typ at IO=20 mA; (3)D terminal leakage current, TO(off): 50A max at VI=0 V; (4)voltage gain (closed loop), AV: 13.4 dB typ; (5)input impedance of amp, RI: 200 k typ.
