Rev.1.0
Sep.17.2003
Description
M62420SP/FP/AFP is the tone and volume controller which is controlled by I2C bus. This IC can apply the broad
application because of low noise and distortion.
M62420AFP changes the slave address from M62420FP.
Features
• TONE(Bass/Treble) control and 1 dB step volume control are enabled.
• Low noise and low distortion .
VNO = 4.5 µVrms, CTHD=0.1% max
• Controlling by serial data in conformity to the I2C bus format .
Applications
• TV, Mini-Stereo, etc
Recommended Operating Condition
• Supply voltage range: 8.5 to 9.5 V (analog) 4.5 to 5.5 V (digital)
• Rated supply voltage: 9 V (analog) 5 V (digital)
