- Figure 1. Amplifier with Dpot pseudologarithmic gain control that runs away at zero and 28
- Figure 2. Pseudologarithmic gain goes off the chart for codes below 24 and above 232
- Figure 3. Add two fixed resistors to bound the gain range to the recommended limits while keeping full 8-bit resolution
- Figure 4. Two added resistors limits gain to recommended 0.1 to 10 range without sacrificing resolution. The red curve shows the result
