Note 1: See the Definitions section at the end of the data sheet.
Note 2: Tested with alternating channels modulated at full scale and ground.
Note 3: See the Input Range and Protection section for more details.
Note 4: C
Note 5: Defined as the change in positive full scale caused by a ±2% variation in the nominal supply voltage.
Note 6: It is recommended that RD, WR, and CS are kept high for the quiet time (t
Note 7: Guaranteed by design.
