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 1/3VDD selects offset
binary output format and turns the clock duty cycle stabi-
lizer on. Connecting MODE to 2/3VDD selects 2’s comple-
ment output format and turns the clock duty cycle stabi-
lizer on. Connecting MODE to VDD selects 2’s complement
output format and turns the clock duty cycle stabilizer off.
SENSE (Pin 59): Reference Programming Pin. Connecting
SENSE to VCM selects the internal reference and a ±0.5V
input range. Connecting SENSE to VDD selects the internal
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
±VSENSE. ±1V is the largest valid
input range.
VCM (Pin 60): 1.6V Output and Input Common Mode Bias.
Bypass to ground with 2.2
F ceramic chip capacitor.
GND (Exposed Pad) (Pin 65): ADC Power Ground. The
exposed pad on the bottom of the package needs to be
soldered to ground.
