MODE (Pin 58): Output Format and Clock Duty Cycle
Stabilizer Selection Pin. Connecting MODE to 0V selects
offset binary output format and turns the clock duty cycle
stabilizer off. Connecting MODE to 1/3V
binary output format and turns the clock duty cycle stabi-
lizer on. Connecting MODE to 2/3V
ment output format and turns the clock duty cycle stabi-
lizer on. Connecting MODE to V
output format and turns the clock duty cycle stabilizer off.

reference and a ±1V input range. An external reference
greater than 0.5V and less than 1V applied to SENSE
selects an input range of ±V
