2ch Electronic Volume with Dynamic Bass Boost

ꢀGENERAL DESCRIPTION

ꢀPACKAGE OUTLINE

The NJW1201A is a 2-channel electronic volume with Dynamic

Bass Boost. 5+1diff-in 1-out selector. It includes 5+1diff input

selector, 1st-volume, 2nd-volume, 3 band Tone, Sound mode,

Dynamic Bass Boost. The NJW1201A performs low noise and low

distortion characteristics with resistance ladder circuit.

All of functions are controlled by I²C BUS interface.
