NOTES:
1. Full scale input range, V
REF
+ - V
REF
-, may be in the range of 0.5V to V
AA
+ -V
AA
- volts. Linearity errors increase at lower full scale ranges,
however.
2. Input current is due to energy transferred to the input at the start of the sample period. The average value is dependent on input and VDD
voltage.
3. The CLK input is a CMOS inverter with a 50k
feedback resistor. It operates from the V
AA
+ and V
AA
- supplies. It may be AC-coupled
with a 1V
P-P
minimum source.
4. Parameter not tested, but guaranteed by design or characterization.
