The A2430 is a digital audio power amplifier IC with.
Maximum output
maximum output of 2.1W (RL = 4Ω) x 2ch, which directly drives speakers while reducing distortion of pulse output signal and reducing noise on the signal, and realizes the highest standard low distortion rate
2.1W x 2ch (VDDP = VDDA = 5.0V, RL = 4Ω, THD+N = 1%) 0.75W x 2ch
characteristics and low noise characteristics . (VDDP = VDDA = 3.6V, RL = 8Ω, THD+N = 10%).
