ML2009CQ中文资料MICRO-LINEAR数据手册PDF规格书

GENERAL DESCRIPTION

The ML2008 and ML2009 are digitally controlled logarithmic gain/attenuators with a range of –24 to +24dB in 0.1dB steps.

Easy interface to microprocessors is provided by an input latch and control signals consisting of chip select and write.
