STA540_Audio Amplifier Ic.
Product Code: AIT012Category: Amplifier IC/Transistor
STA540_Audio Amplifier Ic.
The STA540 is a 4-channel, class-AB audio amplifier designed for high quality sound applications. The amplifiers have single-ended outputs with integrated short-circuit protection, thermal protection and diagnostic functions.
Features
■ High output power capability
– 2x 38 W into 4 Ω at 18 V, 1 kHz, 10% THD
– 2x 34 W into 8 Ω at 22 V, 1 kHz, 10% THD
– 2x 24W into 4Ω at 14.4 V, 1 kHz, 10% THD
– 2x 15 W into 8 Ω at 16 V, 1 kHz, 10% THD
– 4x 13 W into 2 Ω at 15 V, 1 kHz, 10% THD
– 4x 11 W into 4 Ω at 18 V, 1 kHz, 10% THD
– 4x 7 W into 4 Ω at 14.4 V, 1 kHz, 10% THD
■ Minimum external components count:
– no bootstrap capacitors
– no Boucherot cells
– internally fixed gain 20 dB
■ Standby function (CMOS compatible)
■ No audible pop during standby operations
■ Diagnostic facilities:
– clip detector
– output to GND short-circuit detector
– output to VS short-circuit detector
– soft short-circuit check at turn-on
– thermal shutdown warning
Protection
■ Output AC/DC short circuit
■ Soft short-circuit check at turn-on
■ Thermal cutoff/limiter to prevent chip from
overheating
■ High inductive loads
■ ESD
