ML2003 Logarithmic Gain/Attenuator

The ML2003 and ML2004 are digitally controlled logarithmic 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 i.
