ML2003I Datasheet PDF - Fairchild

●General Description

●The ML2003 and ML2004 are digitally controlled logarith mic gain/attenuators with a range of –24 to +24 dB in 0.1 dB steps.

●The gain settings are selected by a 9-bit digital word. The ML2003 digital interface is either parallel or serial. The ML2004 is packaged in a 14-pin DIP with a serial interface only.
