2.8 Serial 10-bit 4-channel D/A Converter (Optional)
The 56F8323EVM board contains the provions for a user to provide a serial 10-bit, 4-channel
D/A converter connected to the 56F8323’s SPI #0 port. The output pins are uncommitted and are
connected to a 4x2 header, J4, to allow easy user connections. Refer to
connections and
be set to a value from +0.0V to +2.4V by a trimpot, R48. If this trimpot is preset to +2.05V, it
would provide approximately +2mV per step. If another device must be used with SPI #0’s
MISO signal and with the D/A converter on the board, the daisy chain jumper, JG9, can be used
to extend or isolate the serial chain.
