General Description
The NJW1195A is a 4-channel electronic volume with 4-in 2-out stereo audio selector. It performs low noise and low distortion characteristics with resistance ladder circuit.The NJW1195A is also available for 2-channel differential transmission electronic volume with 2-in 1-out stereo audio selector by a differential transmission select function.All of functions are controlled via three-wired serial bus.Selectable 4-Chip address is available for using four chips on same serial bus line.Its suitable for two-channel stereo system and or multi-channel audio system.At the volume attenuated, the NJW1195A improves low distortion compared with NJW1195. Furthermore, the NJW1195A supports both single power supply operation and dual power supply operation.
