NOTE:
6. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
7. FSR = Full Scale Range = VREF/Gain
8. Gain accuracy is calibrated at the factory (AVDD = +5V).
9. Specified for word rate equal to 10Sps.
Electrical Specifications VREF+ = 5V, VREF- = 0V, AVDD = 5V, DVDD = 5V, AGND = DGND = 0V, MCLK = 4.9152MHz, and
TA = -40°C to +105°C, unless otherwise specified. Boldface limits apply over the operating temperature range, -40°C to +105°C (Continued)
