Electrical Characteristics: Unless otherwise noted, all parameters apply at V DD = 5V, V REF = 5V, T A = -40°C to +125°C, f SAMPLE = 200 ksps and f SCLK = 18*f SAMPLE = 3.6 MHz. Unless otherwise noted, typical values apply for V DD = 5V and T A = +25°C.

Note 1: This parameter is established by characterization and not 100% tested.

2: See graphs that relate linearity performance to V REF levels.

• 3: Because the sample cap will eventually lose charge, effective clock rates below 10 kHz can affect linearity performance, especially at elevated temperatures. See Section 6.2 'Maintaining Minimum Clock Speed' , 'Maintaining Minimum Clock Speed', for more information.
• 4: This parameter specification applies to industrial temperature grading device option (-40°C to +85°C).
• 5: This parameter specification applies to automotive grade 1 device option (-40°C to +125°C).

• † Notice: Stresses above those listed under 'Absolute Maximum Ratings' may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operational listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability.
