NOTES:

6. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.

7. The device may become nonresponsive if the minimum acquisition times are not met in their respective modes, requiring a power cycle to restore

normal operation.

8. Transition time to high impedance state is dominated by RC loading on the SDOUT pin. Specified value is measured using equivalent loading shown

in Figure 2.

Electrical Specifications VREF = VDD V, VDD = 2.7V to 5V, VCM=VDD/2,SCLK=20MHzandTA=-40°Cto+125°C(typicalperformance

at +25°C), unless otherwise specified. Boldface limits apply over the operating temperature range, -40°C to +125°C. (Continued)
