LA4270

Ordering number : EN1272740FC LA4270 Monolithic Linear IC 6W Dual-Channel AF Power Amplifier Overview The LA4270 is a High-output dual-channel AF Power IC. (PO = 6.0W×2, VCC = 25V, RL = 8Ω, f = 1kHz, THD = 1.0%) Features Low distortion (THD = 0.1%, VCC = 25V, RL = 8Ω, f = 1kHz, PO = 2W). Minimum number of external parts required (no bootstrap capacitor required). Low pop noise at the time of power switch ON/OFF. High ripple rejection (58dB typ). Wide supply voltage range (10V to 32V). On-chip protector against abnormality (thermal shutdown, overvoltage).
