SPECIFICATIONS
ELECTRICAL
T
*Same specification as ADC774JH, JP, SH.
NOTES: (1) With fixed 50 resistor from Ref Out to Ref In. This parameter is also adjustable to zero at +25C. (2) FS in this specification table means Full Scale Range.
That is, for a 10V input range FS means 20V; for a 0V to +10V range, FS means 10V. The term Full Scale for these specification instead of Full-Scale Range is used
to be consistent with other vendors' specifications tables. (3) Using internal reference. (4) See “Controlling the ADC774” section for detailed information concerning
digital timing. (5) The Harris HI-774 uses a subranging/error correction technique that allows one to begin conversion before a preceding sample-hold or multiplexer
has settled to 1/2LSB. For 12-bit accurate conversions, the input transient to the ADC774 must settle to less than 1/2LSB before conversion is started. The ADC774
is compatible with HI-774 in all other respects. (6) External loading must be constant during conversion. The reference output requires no buffer amplifier with either
