DescriptionThe AN7338K is a monolithic IC developed for portable cassette recorder.It is placed in the stage between preamplifier and power amplifier and is operating as a preset graphic equaliser with 5 preset modes:rock, pops, flat, classic and jazz.The boosting frequencies are 100Hz and 7kHz.There is a built-in LED indicator for every mode and FLAT will be the initial mode when power up.
The AN7338K has the following features including:(1)few external components.; (2)selection modes:rock, pops, flat, classic and jazz.; (3)built-in switches can be controlled by microprocessor.; (4)internal LED driver indicator for every mode.If the previous stage has high output impedance (Zout), this may cause the output drop at high frequency.In this situation, the following circuit is recommended to improve the high frequency performance.
The absolute maximum ratings of the AN7338K are:(1)supply voltage:14V;(2)supply current:50mA;(3)power disspation:70mW; (4)storage temperature:-55 to 150; (5)operating ambient temperature:-25 to 75.The products described in this document are designed, developed and manufactured as contemplated for general use, including without limitation, ordinary industrial use, general office use, personal use, and household use, but are not designed, developed and manufactured as contemplated (1) for any use that includes fatal risks or dangers that, unless extremely high safety is secured, could have a serious effect to the public, and could lead directly to death, personal injury, severe physical damage or other loss (i.e., nuclear reaction control in nuclear facility, aircraft flight control, air traffic control, mass transport control, medical life support system, missile launch control in weapon system), or (2) for any use where chance of failure is intolerable (i.e., submersible repeater and artificial satellite).
At present there is not too much information about this model.If you are willing to find more about AN7338K, please pay attention to our web! We will promptly update the relevant information.
