NOTES: (1) COB = Complementary Offset Binary. (2) Complementary Two’s Complement—obtained by inverting the most significant bit MSB (pin 1). (3) CSB
= Complementary Straight Binary. (4) Voltages given are the nominal value for transition to the code specified.

NOTES: (1) The convert command must be at least 50ns wide and must remain low during a conversion. The conversion is initiated
by the “trailing edge” of the convert command. (2) 57
