M62431FP

7-ELEMENT GRAPHIC EQUALIZER WITH MICROCOMPUTER INTERFACE

DESCRIPTION

The M62431FP is 2-channel 7-band graphic equalizer IC developed for home audio, car audio sets, etc. This
IC can be control by serial data from microcomputer.

FEATURES

Be able to operate with serial data from microcomputer
Can be gaining control of 7-band (±10dB and 2dB steps)
Power supply is single power supply or ± power supplies
Low nose VNO (flat)=5µVrms (typ)<JIS-A>
Low distortion THD=0.005% (typ)<HPF400Hz, LPF30kHz>

RECOMMENDED OPERATING CONDITION

Supply voltage range............AVDD, AVss=±4.5 to ±7.0V

(2 power supplies)
Or, AVDD=9 to 14V
(Single power supply AVss=0V)
DVDD=4.5 to 5.5V
(However, DVDD≤AVDD)
