DIGITAL INTERFACE CONNECTIONS
The ADS1255/6 5V tolerant SPI-, QSPI
, and
MICROWIRE
-compatible interface easily connects to a
wide variety of microcontrollers. Figure 26 shows the basic
connection to TI’s MSP430 family of low-power
microcontrollers. Figure 27 shows the connection to
microcontrollers with an SPI interface like TI’s MSC12xx
family or the 68HC11 family. Note that the MSC12xx
includes a high-resolution A/D converter; the ADS1255/6
can be used to add additional channels of measurement
or provide higher-speed conversions. Finally, Figure 28
shows how to connect the ADS1255/6 to an 8xC51 UART
in serial mode 0 in a 2-wire configuration. Avoid using the
continuous read mode (RDATAC) when DIN and DOUT
are connected together.
