NJW5211
8bit 8ch D/A Converter
s
GENERAL DESCRIPTION
The NJW5211
is 8bit 8ch D/A converter for electronic adjustment.
8ch DC out put can be independently controlled by three-wire serial
interface.
The NJW5211
features low operating voltage(2.7V) and can be full-swing
outputted regardless of supply voltage.
