CONDITIONS
Notes:
1. Available for external loads. External load should not change during conversion. When supplying an
external load and operating on a +12V supply, a buffer amplifier must be provided for the reference
output.
2. Minimum resolution for which no missing codes are guaranteed.
3. Externally adjustable to zero. See Calibration information.
4. Fixed 50Ω resistor between REF OUT and REF IN.
5. Specifications are identical for all models unless otherwise noted.
