Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All voltage values are with respect to network ground terminal.

LSB means least significant bit. For the 12-bit, ±10-V input ADS8504, one LSB is 4.88 mV.
Typical rms noise at worst case transitions and temperatures.
As measured with fixed resistors shown in
Figure 23
. Adjustable to zero with external potentiometer.
Full-scale error is the worst case of -full-scale or +full-scale deviation from ideal first and last code transitions, divided by the transition
voltage (not divided by the full-scale range) and includes the effect of offset error.
