SHDNA (Pin 59): Channel A Shutdown Mode Selection
Pin. Connecting SHDNA to GND and OEA to GND results
in normal operation with the outputs enabled. Connecting
SHDNA to GND and OEA to VDD results in normal opera-
tion with the outputs at high impedance. Connecting
SHDNA to VDD and OEA to GND results in nap mode with
the outputs at high impedance. Connecting SHDNA to VDD
and OEA to VDD results in sleep mode with the outputs at
high impedance.
MODE (Pin 60): Output Format and Clock Duty Cycle
Stabilizer Selection Pin. Note that MODE controls both
channels. Connecting MODE to GND selects offset binary
output format and turns the clock duty cycle stabilizer off.
1/3 VDD selects offset binary output format and turns the
clock duty cycle stabilizer on. 2/3 VDD selects 2’s comple-
ment output format and turns the clock duty cycle stabi-

lizer on. VDD selects 2’s complement output format and
turns the clock duty cycle stabilizer off.
VCMA (Pin 61): Channel A 1.5V Output and Input Common
Mode Bias. Bypass to ground with 2.2
F ceramic chip
capacitor. Do not connect to VCMB.
SENSEA (Pin 62): Channel A Reference Programming Pin.
Connecting SENSEA to VCMA selects the internal reference
and a
±0.5V input range. VDD selects the internal reference
and a
±1V input range. An external reference greater than
0.5V and less than 1V applied to SENSEA selects an input
range of
±VSENSEA. ±1V is the largest valid input range.
GND (Exposed Pad) (Pin 65): ADC Power Ground. The
Exposed Pad on the bottom of the package needs to be
soldered to ground.
