Electrical Characteristics
Electrical Characteristics
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not apply when operating
the device beyond its specified operating conditions.
Note 2: All voltages are measured with respect to GND, unless otherwise specified.
Note 3: A zener diode exists, internally, from V
Note 4: Two on-chip diodes are tied to each analog input which will forward conduct for analog input voltages one diode drop below ground or one diode drop greater
than the V
than 100 mV, the output code will be correct. To achieve an absolute 0 V
V
Note 5: Total unadjusted error includes offset, full-scale, and linearity errors. See Figure 3 . None of these A/Ds requires a zero or full-scale adjust. However, if an
all zero code is desired for an analog input other than 0.0V, or if a narrow full-scale span exists (for example: 0.5V to 4.5V full-scale) the reference voltages can be
adjusted to achieve this. See Figure 13 .
Note 6: Comparator input current is a bias current into or out of the chopper stabilized comparator. The bias current varies directly with clock frequency and has little
temperature dependence ( Figure 6 ). See paragraph 4.0.
Note 7: If start pulse is asynchronous with converter clock or if f

Note 8: The outputs of the data register are updated one clock cycle before the rising edge of EOC.
