Applications Information
(Continued)
the first SCLK edge after CS goes low is a rising edge, all
four leading zeroes will be valid on the first four falling edges
of SCLK. If instead the first SCLK edge after CS goes low is
a falling edge, the first leading zero may not be set up in time
for a microprocessor or DSP to read it correctly. The remain-
ing data bits are still clocked out on the falling edges of
SCLK.
3.0 ADCS7476/77/78 TRANSFER FUNCTION
The output format of the ADCS7476/77/78 is straight binary.
Code transitions occur midway between successive integer
LSB values. The LSB widths for the ADCS7476 is V
DD
/
4096; for the ADCS7477 the LSB width is V
/ 1024; for the
ADCS7478, the LSB width is V
/ 256. The ideal transfer
characteristic for the ADCS7476 and ADCS7477 is shown in
Figure 6, while the ideal transfer characteristic for the
ADCS7478 is shown in Figure 7.
