(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is ensured to be functional, but do not ensure specific performance limits. For ensured specifications and test

conditions, see the Electrical Characteristics. The ensured specifications apply only for the test conditions listed. Some performance

characteristics may degrade when the device is not operated under the listed test conditions. Operation of the device beyond the

maximum Operating Ratings is not recommended.

(2) All voltages are measured with respect to GND = AGND = DGND = 0V, unless otherwise specified.

Converter Electrical Characteristics

Unless otherwise specified, the following specifications apply for AGND = DGND = DRGND = 0V, V_A= V_D= +3.3V, V_DR

+2.5V, Internal V_REF= +1.0V, f_CLK= 65 MHz, f_IN= 5 KHz, C_L= 15 pF/pin. Boldface limits apply for T_J= T_MINto T_MAX: all

other limits T_J= 25°C^(1)(2)(3)(4)

(1) The inputs are protected as shown below. Input voltage magnitudes above V_Aor below GND will not damage this device, provided

current is limited per. However, errors in the A/D conversion can occur if the input goes above V_Aor below GND by more than 100 mV.

As an example, if V_Ais +3.3V, the full-scale input voltage must be ≤+3.4V to ensure accurate conversions.

(2) To ensure accuracy, it is required that |V_A–V_D| ≤ 100 mV and separate bypass capacitors are used at each power supply pin.

(3) With the test condition for V_REF= +1.0V (2V_P-Pdifferential input), the 12-bit LSB is 488 µV.

(4) When the input voltage at any pin exceeds the power supplies (that is, V_IN< AGND, or V_IN> V_A), the current at that pin should be

limited to 25 mA. The 50 mA maximum package input current rating limits the number of pins that can safely exceed the power supplies

with an input current of 25 mA to two.

(5) Typical figures are at T_A= 25°C, and represent most likely parametric norms at the time of product characterization. The typical

specifications are not ensured.
