NOTES: (1) With fixed 50Ω resistor from REF OUT to REF IN. This parameter is also adjustable to zero at +25°C. (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. (3) Maximum error at TMIN and TMAX. (4) Based on using VEE
=
+5V, which is the Control Mode. See the section "S/H Control Mode and ADC774 Emulation Mode." (5) Using internal reference. (6) This is worst case change
in accuracy from accuracy with a +5V supply. (7) VEE is optional, and is only used to set the mode for the internal sample/hold. When VEE = –15V, IEE = –1mA
typ; when VEE = 0V, IEE = ±5µA typ; when VEE = +5V, IEE = +167µA typ.
