NTE1675
Integrated Circuit
Dual AF Power Amp, 8.5W
Features:
D Small idling current (20mA/2 channels) enabling prolonged battery life.
D Small dependence of idling current on V_CC.
D High power (8.5W typ. X 2).
D High ripple rejection (60dB at steady state). Since filters are arranged in 3 stages (including 1
stage inside IC) to attain satisfactory ripple rejection at transient state, ripple occurring at the
time of motor start can be prevented from mising in.
D Small pop noise at the time of power supply ON/OFF and good starting balance between both
channels (0.6 sec) due to built−in pop noise limiter.
D Pins provided for compensating high frequency response.
D Small residual noise (0.4mV).
D Wide supply voltage range (6 to 24V) easing design of transformer power supply.
D Built−in thermal shutdown circuit.
D Designed so that inverse insertion or short between adjacent pins causes no destruction.
D Channel−to−channel mirror image pin assignment and provision of Pre GND, Power GND
pins enabling stable operation and easing artwork of printed circuit board.
D Minimum number of external parts required (9 pcs. min, 12 pcs. typ)
D Audio muting capability (for automatic music selection, electronic tuner).
