A2430 Datasheet | AiT Semiconductor

DESCRIPTION FEATURES 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%) - Distortion Rate (THD+N) The A2430 detects output signal clip due to the over 0.03 % level input signal and suppress the output signal clip automatically. Also the non-clip output control (VDDP = VDDA = 3.6V, RL = 8Ω, PO = 0.4W, 1k Hz) function can adapt the output clip caused by power - Efficiency supply voltage down with battery. Attack time and 84 % (VDDP = VDDA = 3.6V, RL = 8Ω, PO == release time can be freely set by external resistances 600m W) or capacitances. - Channel separation The independent power-down function for L channel 95d B and R channel minimizes consumption current at (VDDP = VDDA = 3.6V, RL = 8Ω, AV = 18d B, 1k Hz) standby. As for protection function, short-current - Non-clip output protection function for speaker output terminal, - 2ch independent power-down control function over-temperatue protection function for inside of the - Thermal Protection function device, and low supply voltage malfunction - Available in QFN20(4x4) package. preventing function are prepared. The A2430 is available in QFN20(4x4) package.
