TEMP_OUT

Provides an output voltage proportional to the chip temperature, typically

1.46 V at 25°C with an output variation of 4.4 mV/°C.

38

40

SIGGND0

Reference Ground for DAC 0 to DAC 3. VOUT0 to VOUT3 are referenced to this

voltage.

43, 51

45, 53

DGND

Ground for All Digital Circuitry. Both DGND pins should be connected to the

DGND plane.

44, 50

46, 52

Logic Power Supply; 2.5 V to 5.5 V. These pins should be decoupled with 0.1 μF

ceramic capacitors and 10 μF capacitors.

SYNC

Active Low or SYNC Input for SPI Interface. This is the frame synchronization

signal for the SPI serial interface. See

,

, and the

section for more details.

SCLK

Serial Clock Input for SPI Interface. See Figure 4, Figure 5, and the Serial Interface

section for more details.

SDI

Serial Data Input for SPI Interface. See Figure 4, Figure 5, and the Serial Interface

section for more details.

48

50

PEC

Packet Error Check Output. This is an open-drain output with a 50 kΩ pull-up

that goes low if the packet error check fails.

49

51

SDO

Serial Data Output for SPI Interface. See Figure 4, Figure 5, and the Serial

Interface section for more details.

AGND

Ground for All Analog Circuitry. The AGND pin should be connected to the

AGND plane.
