1 −DIN Negative Input. 2 VOCM Common-Mode Output Voltage. Voltage applied to this pin sets the common-mode output voltage with a ratio of 1:1. For example, 1 V dc on VOCM will set the dc bias level on +OUT and −OUT to 1 V. 3 V+ Positive Supply Voltage. 4 +OUT Positive Output. Note: the voltage at −DIN is inverted at +OUT. 5 −OUT Negative Output. Note: the voltage at +DIN is inverted at −OUT. 6 V− Negative Supply Voltage. 7 NC No Connect. 8 +DIN Positive Input. Rev.
