STEREO 2.1W NON-CLIP

AUDIO AMPLIFIER

DESCRIPTION

FEATURES

The A2430 is a digital audio power amplifier IC with

maximum output of 2.1W (R_L= 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

characteristics and low noise characteristics .



Maximum output

2.1W x 2ch

(V_DDP= V_DDA= 5.0V, R_L= 4Ω, THD+N = 1%)

0.75W x 2ch

(V_DDP= V_DDA= 3.6V, R_L= 8Ω, THD+N = 10%)

Distortion Rate (THD+N)



The A2430 detects output signal clip due to the over

level input signal and suppress the output signal clip

automatically. Also the non-clip output control

function can adapt the output clip caused by power

supply voltage down with battery. Attack time and

release time can be freely set by external resistances

or capacitances.

0.03 %

(V_DDP= V_DDA= 3.6V, R_L= 8Ω, P_O= 0.4W, 1kHz)

Efficiency

84 % (V_DDP= V_DDA= 3.6V, R_L= 8Ω, P_O==

600mW)

Channel separation

95dB

The independent power-down function for L channel

and R channel minimizes consumption current at

standby. As for protection function, short-current

protection function for speaker output terminal,

over-temperatue protection function for inside of the

device, and low supply voltage malfunction

preventing function are prepared.

(V_DDP= V_DDA= 3.6V, R_L= 8Ω, A_V= 18dB, 1kHz)

Non-clip output
