LA4708N Description
ENA1783A LA4708N Monolithic Linear IC 20W 2-channel BTL AF Power Amplifier for Car Stereo http://onsemi. Overview The LA4708N is a BTL two-channel power IC for car audio developed in pursuit of excellent sound quality. Low-region frequency characteristics have been improved through the use of a new NF capacitor-less circuit, and crosstalk which causes “muddy” sound has been reduced by improving both circuit and...
LA4708N Key Features
- High power : supports total output of 30W 30W (VCC = 13.2V, THD = 30%, RL = 4)
- Supports RL = 2 (PO = 30W when VCC = 13.2V, THD = 10%)
- Designed for excellent sound quality (fL 10Hz, fH = 130kHz)
- NF capacitor-less
- Any on time settable by external capacitor
- Less pop noise
- Standby switch circuit on chip (microprocessor supported)
- Various protectors on chip (output-to-ground short/output-to-VCC short/load short/overvoltage/thermal shutdown circuit)
- Set VCC, RL in a range that does not exceed Pd max = 37.5W
