UTC386

UTC386 LI NEAR I NTEGRATED CI RCUI T LOW VOLTAGE AUDIO POWER AMPLIFIER DESCRIPTION The UTC386 is a power amplifier designed for use in low voltage consumer applications. The gain is internally set to 20 keep the external part count low, but the additional of external resistor and capacitor between pin 1 and pin 8 will increase the gain to any value up to 200. FEATURES *Battery operation *Minimum external parts *Wide supply voltage range:4V~12V *Low quiescent current drain(4mA) *Voltage gains:20~200 *Ground referenced input *Self -centering output quiescent voltage *low distortion DIP-8 BLOCK DIAGRAM 6 VCC 7 Bypass 15kΩ 15kΩ 8 Gain 1 Gain 15kΩ Gain 5 Output 3 +Input 1 8 Gain -Input 2 7 Bypass 2 -Input 150Ω 1.35kΩ UTC386 +Input 3 6 VCC 50kΩ 50kΩ 4 GND GND 4 5 Output ABSOLUTE MAXIMUM RATINGS(Ta=25°C ) Characteristic Supply Voltage Power Dissipation Input voltage Operating Temperature Storage Temperature Symbol Vcc Pd Vi Topr Tstg Value 15 660 -0.4~+0.4 -20 to 70 -40 to 125 Unit V mW V °C °C YOUW ANG ELECTRONI CS CO.
