ADC
analog-to-digital converter–an electronic device, often an integrated
circuit, that converts an analog voltage to a digital number
AIGND
analog input ground signal
AOGND
analog output ground signal
AWG
American Wire Gauge
B
BCD
binary-coded decimal
bus
the group of conductors that interconnect individual circuitry in a
computer. Typically, a bus is the expansion vehicle to which I/O or
other devices are connected. Examples of PC buses are the AT bus,

CE
card enable signal
CGND
chassis ground signal
channel
pin or wire lead to which you apply or from which you read the analog
or digital signal. Analog signals can be single-ended or differential. For
digital signals, you group channels to form ports. Ports usually consist
of either four or eight digital channels.
CJSENSOR
cold-junction sensor
CLK
clock input signal
CMOS
complementary metallic oxide semiconductor
CMRR
common-mode rejection ratio
