NOTES: (1) With fixed 50Ω resistor from REF OUT to REF IN. This parameter is also adjustable to zero at ±25°C (see Optional External Full Scale and Offset
Adjustments section). (2) FS in this specification table means Full Scale Range. That is, for a ±10V input range, FS means 20V; for a 0 to +10V range, FS means
10V. The term Full Scale for these specifications instead of Full-Scale Range is used to be consistent with other vendors' 574 and 574A type specifications tables.
(3) Using internal reference. (4) See Controlling the ADC574A section for detailed information concerning digital timing. (5) External loading must be constant during
conversion. The reference output requires no buffer amplifier with either ±12V or ±15V power supplies.
