The BA681A is a monolithic IC for LED power meter applications. The display level range is 6mVrms to 359mVrms (Typ.) divided into 12 points with repeated interval spacings of 3dB, 3dB and 4dB. The 0dB level is 180mVrms (Typ.) and the range is -30dB to +16dB. The constant current outputs can be set using external components allowing use of different color LEDs in various combinations.
