NOTES:
1. This bias is internally arranged to track the input voltage at INPT; it is not specified relative to ground.
2. The deviation of VLOG from the ideal relationship expressed as VLOG = Slope × (IPD - IZ) with quantities expressed in
logarithmic (dB) scale.
3. The specified minimum and maximum values are guaranteed by ATE, excluding the reliability shift.
4. Output noise and incremental bandwidth are functions of the input current.
