Typical Performance Characteristics, DNL, INL
Unless otherwise specified, the following specifications apply: AGND = DGND = DRGND = 0V, V_A = V_D = +3.3V, V_DR =
+1.8V, Internal V_REF = +1.0V, f_CLK = 155 MHz, V_CM = V_RM, C_L = 5 pF/pin, Single-Ended Clock Mode, Offset Binary Format.
Typical values are for T_A = 25°C. Boldface limits apply for T_MIN ≤ T_A ≤ T_MAX. All other limits apply for T_A = 25°C^(1)(2)(3)

(1) The inputs are protected as shown below. Input voltage magnitudes above V_A or below GND will not damage this device, provided
current is limited see Note 4 in the Absolute Maximum Ratings table. However, errors in the A/D conversion can occur if the input goes
above 2.6V or below GND as described in the Operating Ratings section (See Figure 2).
(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-P differential input), the 14-bit LSB is 122.1 µV.
