FIGURE 23. Low Voltage Peak Detector with Rail-to-Rail Peak Capture Range
In Figure 23 dielectric absorption and leakage is minimized
by using a polystyrene or polyethylene hold capacitor. The
droop rate is primarily determined by the value of CH and
diode leakage current. The ultra-low input current of the
LMC6482 has a negligible effect on droop.

FIGURE 24. Rail-to-Rail Sample and Hold
The LMC6482’s high CMRR (82dB) allows excellent accu-
racy throughout the circuit’s rail-to-rail dynamic capture
range.
