Term Definition
Data Transfer The time during which data is transferred from DOUT and to DIN. The interval
Interval is 16 shift clocks and the data transfer is initiated by the falling edge of the FS
signal in standard and continuous mode.
Signal Data This refers to the input signal and all of the converted representations through
the ADC channel and the signal through the DAC channel to the analog output.
This is contrasted with the purely digital software control data.
Frame Sync Frame sync refers only to the falling edge of the signal FS that initiates the data
transfer interval
Frame Sync and Sampling Frame sync and sampling period is the time between falling edges of
Period successive FS signals.
f
s
The sampling frequency
ADC Channel ADC channel refers to all signal processing circuits between the analog input
and the digital conversion result at DOUT.
DAC channel DAC channel refers to all signal processing circuits between the digital data
word applied to DIN and the differential output analog signal available at OUTP
and OUTM.
Dxx Bit position in the primary data word (xx is the bit number)
DSxx Bit position in the secondary data word (xx is the bit number)
PGA Programmable gain amplifier
