LA4500

Ordering number:ENN1164C Monolithic Linear IC LA4500 5.3W 2-Channel AF Power Amplifier Features Low idling current (20mA/2 channels) enabling prolonged battery life. Less dependence of idling current on VCC. High power (5.3W typ. ×2). High ripple rejection (60dB at steady state). Since filters are arranged in 3 stages (including 1 stage inside the IC) to attain satisfactory ripple rejection at transient state, ripple occuring at the time of motor start can be prevented from mixing in. Low pop noise at the time of power supply ON/OFF and good starting balance between both channels (0.6s.) due to built-in pop noise limiter. Pins provided for compensating high frequency responce. Low residual noise (0.4mV). Wide supply voltage range (6 to 24V) fascilitating design of transformer power supply. Built-in thermal shutdown circuit, Designed so that inverse insertion or short between adjacent pins causes no destruction. Channel-to channel mirror image pin assignment and provision of Pre GND, Power GND pins enabling stable operation and fascilitating artwork of printed circuit board. Minimum number of external parts required (9pcs. min., 12pcs. typ.). Audio muting capability (for automatic music selection, electronic tuner).
