Typical Applications
(Continued)
3-Decade Logarithmic A D Converter
Noise Filtering the Analog Input
f C e 20 Hz
Uses Chebyshev implementation for steeper roll-off
unity-gain 2nd order low-pass filter
Adding a separate filter for each channel increases
system response time if an analog multiplexer
is used
Multiplexing Differential Inputs
Output Buffers with A D Data Enabled
A D output data is updated 1 CLK period
prior to assertion of INTR
Increasing Bus Drive and or Reducing Time on Bus
Allows output data to set-up at falling edge of CS
