|
Steps |
| Number of discrete output states available from the DAC. | |
|
Control Bits |
| Number of digital control bits | |
|
Resolution |
| Maximum output resolution based on number of control bits. | |
|
|
Voltage Resolution |
| Specifies the Resolution per digital bit in terms of Voltage. | |
|
SPI Connections |
|
|
Channel |
| SPI Channel selector | |
|
|
Prescale |
| Prescale option selector | |
|
MOSI |
| SPI Data Out Pin SDO - Also Known as Master Out Slave In (MOSI) when used in Master mode. | |
|
|
MOSI Remap Pin |
| Select which the target pin to assign the MOSI hardware pin functionality. | |
|
|
MISO |
| SPI Data In Pin SDI - Also Known as Master In Slave Out (MISO) when used in Master mode. | |
|
|
MISO Remap Pin |
| Select which the target pin to assign the MISO hardware pin functionality. | |
|
|
CLK |
| SPI Clock Pin CLK - The Clock signal is driven by the SPI master. | |
|
|
CLK Remap Pin |
| Select which the target pin to assign the CLK hardware pin functionality. | |

|
CS / SS |
| Chip Select / Slave Select Pin Master Mode: General purpose output pin used to select the remote SPI device. Slave Mode: Hardware chip select pin input used to select the SPI device. | |
|
Use SHDN Pin |
| Allows the SHDN pin to be driven from an output pin on the microcontroller. If not used then tie the SHDN pin to VCC to allow the DAC to function. | |
|
|
Use LDAC Pin |
| Allows the LDAC pin to be driven from an output pin on the microcontroller. If not used then tie the LDAC pin to GND to allow the DAC to function. | |
