3-Decade Logarithmic A/D Converter

DS005671-73

Noise Filtering the Analog Input

DS005671-74

=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

DS005671-75

Output Buffers with A/D Data Enabled

DS005671-76

*A/D output data is updated 1 CLK period prior to assertion of INTR

Increasing Bus Drive and/or Reducing Time on Bus

DS005671-77

*Allows output data to set-up at falling edge of CS
