2. About the built-in operational amplifiers
The LA8608V has three independent operational amplifiers on chip that can be used as needed. If they are not to be used, short
the I/O pins.
Sample application 1: Noise amplifier
Using the three operational amplifiers, it is possible to form a secondary biquad bandpass filter. (For details on the filter
response characteristics, refer to the data provided later.)
