Figure 8. Pin Configuration (Exposed Pad on bottom of package)
Description
The exposed pad is electrically connected to AV
TQFP with exposed pad on BOTTOM: For enhanced thermal, electrical and board level
performance, the exposed paddle on the bottom of the package should be soldered to a
corresponding thermal land paddle on the PCB.
Negative analog supply voltage
Positive analog supply voltage
Active low logic input used for synchronizing updates within one device or across a group
of devices. If synchronization is not required, LOAD may be tied low and updates to DAC
channels or PMU modes will happen as they are presented to the device. See the BUSY and
LOAD FUNCTIONS section for detailed information.
Digital supply voltage
Analog ground, reference points for force and measure circuitry
Digital ground reference point.
Open Drain active low input/output indicating the status of interface.
Clock input, active falling edge
Comparator output low in SPI mode and SCLK in LVDS interface mode
Comparator output high in SPI mode and SDI in LVDS interface mode
Serial data input
Frame sync, active low
Comparator output low in SPI mode and SYNC in LVDS interface mode
Comparator output high in SPI mode and SDO in LVDS interface mode
