YDA143 Product details

Description

of operating functions. Digital Amplifier Function YDA143 has digital amplifiers with analog input, PWM pulse output, Maximum output of 15W (RL=4Ω) 2ch.Distortion of PWM pulse output signal and noise of the signal is reduced by adopting “Pure Pulse Direct Speaker Drive Circuit” First Stage Amplifier Gain Setting Function YDA143 is composed of the first stage amplifier with gain setting control and 18dB fixed-gain digital amplifier.Gain of the first stage amplifier can be set by GAIN[1:0] t.
