extended commercial temperature range. The output voltage may be
set at any level greater than 2.495V (V REF ) up to 36V merely by
selecting two external resistors that act as a voltage divider network.
These devices have a typical output impedance of 0.2 ? . Active output
circuitry provides very sharp turn-on characteristics, making these
