NOTES
1Adjustable to zero with external potentiometers.
2Includes internal voltage reference error.
3+25°C to TMIN and +25°C to TMAX
4Excludes internal reference drift.
5Change in gain error as a function of the dc supply voltage.
6Tested under static conditions. See Figure 15 for typical curve of ILOGIC vs. load capacitance at maximum tC.
Specifications subject to change without notice.
