NOTES:
8. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
9. The absolute voltage applied to each analog input must be between GND and +VCC to guarantee datasheet performance.
10. Applies only to +IN.
Electrical Specifications +VCC = +5V, VREF = +5V, fSAMPLE = 12.5kHz, fCLK =16 fSAMPLE , unless otherwise noted. Typical
values are at TA = +25°C. Boldface limits apply over the operating temperature range, -40°C to +85°C. (Continued)
