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.
The interface for gain setting of the ML2008 is by an 8-bit
data word, while the ML2009 is designed to interface to a
16-bit data bus with a single write operation by hard-
wiring the gain/attenuation pin or LSB pin. The ML2008
can be power downed by the microprocessor utilizing a
bit in the second write operation.
Absolute gain accuracy is 0.05dB max over supply
tolerance of
±
10% and temperature range.
These CMOS logarithmic gain/attenuators are designed for
a wide variety of applications in telecom, audio, sonar or
general purpose function generation.
