OUTPUT DATA FORMAT
The AD1671 provides both MSB and MSB outputs, delivering
data in positive true straight binary for unipolar input ranges
and positive true offset binary or twos complement for bipolar
input ranges. Straight binary coding is used for systems that ac-
cept positive-only signals. If straight binary coding is used with
bipolar input signals, a 0 V input would result in a binary output
of 2048. The application software would have to subtract 2048
to determine the true input voltage. Host registers typically per-
form math on signed integers and assume data is in that format.
Twos complement format minimizes software overhead which is
especially important in high speed data transfers, such as a
DMA operation. The CPU is not bogged down performing data
conversion steps, hence the total system throughput is increased.
OPTIONAL EXTERNAL REFERENCE
The AD1671 includes an onboard +2.5 V reference. The refer-
ence input pin (REF IN) can be connected to reference output
pin (REF OUT) or a standard external +2.5 V reference can be
selected to meet specific system requirements. Fast switching in-
put dependent currents are modulated at the reference input.
The reference input voltage can be held with the use of a capaci-
tor. To prevent the AD1671’s onboard reference from oscil-
lating when not connected to REF IN, REF OUT must be
connected to +5 V. It is possible to connect REF OUT to +5 V
due to its output circuit implementation which shuts down the
reference.
