SPI INTERFACE
ADS8507
SLAS381–DECEMBER 2006
APPLICATION INFORMATION (continued)
For the fastest conversion rate, the baud rate should be set to 2 (4.19-MHz SCK), DT set to 10, the first serial
transfer set to 8 bits, the second set to 16 bits, and DSCK disabled (in the command control byte). This allows
for a 23-kHz maximum conversion rate. For slower rates, DT should be increased. Do not slow SCK as this may
increase the chance of affecting the conversion results or accidently initiating a second conversion during the
first 8-bit transfer.
In addition, CPOL and CPHA should be set to zero (SCK normally low and data captured on the rising edge).
The command control byte for the 8-bit transfer should be set to 20
H
and for the 16-bit transfer to 61
H
.
The SPI interface is generally only capable of 8-bit data transfers. For some microcontrollers with SPI interfaces,
it might be possible to receive data in a similar manner as shown for the QSPI interface in
Figure 49
. The
microcontroller needs to fetch the 8 most significant bits before the contents are overwritten by the least
significant bits.
A modified version of the QSPI interface shown in
Figure 50
might be possible. For most microcontrollers with a
SPI interface, the automatic generation of the start-of-conversion pulse is impossible and has to be done with
software. This limits the interface to DC applications due to the insufficient jitter performance of the convert pulse
itself.
