amp specifically for basshorn
what should i consider??
THD ,IM etc..
i know it has to be clean..
is it the unmeasurable or difficult to measure qualities that make it good.
im thinking of class a/b automatically..
it needs to handle 4ohm load<shiva>
but what are my options, probably low power ,about 50watts is fine..<105db/1watt basshorn at home with parents nearby sometimes>
i was thinking of this module too.
The LM1875 is a monolithic power amplifier IC which takes advantage of advanced techniques to achieve low distortion, even at high output levels. Other features include high gain, fast slew rate and a wide power bandwidth, large output voltage swing, high current capability and wide supply range. The device is internally compensated for gains of 10 and greater.
Supply Voltage +/-30V max.
Supply Current 100mA max.
THD 20W/1KHz 0.015% typ.
Open Loop Gain 90dB typ.
Current Limit 4A typ.
(junction to case) 2°C/W typ.
Junction Temperature 150°C max.
