NOTES:
1. Unless otherwise specified, the following conditions apply: Unit is in “sample” mode. VS=±15V, TJ=25°C, -11.5V≤VIN≤11.5V, CH=0.01µF, and
RL=2kΩ. Logic reference voltage=0V and logic voltage=2.5V.
2. Hold step is sensitive to stray capacitive coupling between input logic signals and the hold capacitor. 1pF, for instance, will create an
additional 0.5mV step with a 5V logic swing and a 0.01F hold capacitor. Magnitude of the hold step is inversely proportional to hold capacitor
value.
3. Leakage current is measured at a junction temperature of 25°C. The effects of junction temperature rise due to power dissipation or elevated
ambient can be calculated by doubling the 25°C value for each 11°C increase in chip temperature. Leakage is guaranteed over full input
signal range.
4. These parameters guaranteed over a supply voltage range of ±5 to ±18V.
