UPC1406HA(Audio output Amplifier)
(1) Feature
• Each attenuator is completely separate and is very easy to control with remote control (e.g Volume, Balance)
• This IC’s characteristic control curve is linear against logarithmic output and offers smooth control.
• Channel Seperation : 64dB MIN
• Typical Application : Sound MPX attenuator for TV, Radio and mobil receiver
(2) General Description
• The UPC1406HA is a silicon monolithic integrated circuit for sound control (e, g, Volume, Balance)
This IC has a good characteristic control curve (‘A’ Cuve) and is very suitable for remote control applications.
The two attenuators are completely separate and is easy to control the balance between the two attenuators.
This IC is manufactured in a 9 pin slim SIP.
