Block Diagram of IC for Car Audio or Subwoofer

Functions

Can be used to configure a 2- to 3-dimensional LPF, through the external attachment of 4 low-capacitance capacitors of only 0.01 µF.
Three cutoff frequency types can be freely set through an external control signal.


Reference Characteristics

  • The cutoff frequency can be set to a desired value if capacity is externally attached to the LPF circuit
    (fc=50, 80, 120 Hz @0.01 µF×2×2ch)
  • Distortion: 0.3% max @≤1 kHz, S/N: 78 dB @Vi = 0.775 Vr.m.s., I/O voltage range: 2 Vr.m.s.

Set

Car Audio
(For applications in which low noise is emphasized. Cannot be used in HiFi equipment requiring severe distortion characteristics.)
