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).
