ELECTRICAL CHARACTERISTICS over operating ranges (unless otherwise noted)
Typical values are for T
temperature and supply voltage ranges shown in Operating Ranges.
Notes:
1. When the QSLAC-NP device is in the Inactive mode, the analog output (V
2. Power dissipation in the Inactive mode is measured with all digital inputs at V
