Typical Applications (Continued)

3-Decade Logarithmic A/D Converter

Noise Filtering the Analog Input

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
