NJW1201A
2ch Electronic Volume with Dynamic Bass Boost
!GENERAL DESCRIPTION
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.
