ANALOG SECTION:
6. The overall output current tolerance depends upon the accuracy of the external resistor. Using 1% or better resistor is recommended.
7. The external circuit must not force the I
8. This parameter, derived from the 1 MHz clock, is guaranteed by design, not tested in production.
DIGITAL PARAMETERS SECTION:
