*Same specification as ADS574JE/JH/JP/JU/SF/SH.
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 starts a conversion immediately upon a convert command. Using VEE = 0V to –15V makes the ADS574/ADS774 emulate standard ADC574 operation. In this
mode, the internal sample/hold acquires the input signal after receiving the convert command, and does not assume that the input level has been stable before
the convert command arrives. (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.
