technology. The key to this break through is the use
of EEPROM registers for correction of curvature,
• Enable Pin Allowing a 3µA Shutdown Mode

• 20mA Output Current
architecture that allows package level programming
• Voltage Options 1.8V, 2.048V, 2.5V, 3.0V, 3.3V,
to overcome assembly shift. The shifts in voltage

accuracy and tempco during assembly of die into
plastic packages limit the accuracy of references
• Custom Voltage Options Available (1.8V to
