The LM12 is a power op amp capable of driving g25V at
g10A while operating from g30V supplies. The monolithic
IC can deliver 80W of sine wave power into a 4X load with
0.01% distortion. Power bandwidth is 60 kHz. Further, a
peak dissipation capability of 800W allows it to handle reactive
loads such as transducers, actuators or small motors
without derating.
The LM12 establishes that monolithic ICs can deliver considerable output power without resorting to complex switching schemes. Devices can be paralleled or bridged for even greater output capability. Applications include operational power supplies, high-voltage regulators, high-quality audio amplifiers, tape-head positioners, x-y plotters or other servo-control systems.
Bu entegreyi ilk kez görüyorum. Linear motor driver olduğundan ve 4 ohm da 0.01 % distorsiyondan bahsediyor.
Bu op amp ın bizim ilgilendiğimiz mevzu ile bir alakası yok mu yoksa diyecektim tam, yüksek kaliteli ses yükselticisi olduğunu okudum. Kısacası her derde deva bişey.
Ayrıca biraz pahalı bir parça olduğunu da belirteyim. $32.90
