UPD63310 Product details

Description

OF OPERATIONS 1.1 Analog Input Block The analog input block enables signal input from two channels.Four different stereo signals (IN1 to IN4) and a monaural signal (IN5) can be mixed and input via these channels.The volume can be adjusted for each analog signal, and the sum of the volume settings is input to the ADC.A 6-bit signal is used to adjust the volume within an adjustment range (in 1.5-dB steps) from 46.5 dB to 0 dB, plus a mute setting.

Features

two channels each of on-chip 16-bit ADC and DAC circuits for mutual conversion between digital signals and audio signals (having a maximum signal bandwidth of 24 kHz). The analog signal input block enables mixed input of four different stereo signals and one monaural signal, and the volume of each signal can be controlled before mixing. The µPD63310 also features two on-chip microphone amplifiers (mic amps) and gain is adjustable between 10 and 30 dB. The analog signal output block enables mixed.
