NAME 1 VOUT Analog output of the DAC 2 VCC Positive analog power supply: +15V 3 VSS Negative analog power supply: –15V 4 AGND Analog ground 5 VREFH-F VREFH reference input (Force). Connect to external VREFH. 6 VREFH-S VREFH reference input (Sense). Connect to external VREFH. 7 VREFL-S VREFL reference input (Sense). Connect to external VREFL. 8 VREFL-F VREFL reference input (Force). Connect to external VREFL. 9 VDD Digital power. +5V for 5V interface logic; +3V for 3V logic. Power-On-Reset select. Determines VOUT after power-on reset. If tied to VDD, the DAC latch is set to mid-scale 10 RSTSEL after power-on, and VOUT is (VREFH– VREFL)/2. If tied to DGND, the DAC latch is cleared ('0'), and VOUT is VREFL. 11 RST Reset (active low) 12 CS Chip select input (active low). Data are not clocked into SDI unless CS is low. 13 SCLK Serial clock input 14 SDI Serial data input. Data are latched into input register on the rising edge of SCLK. Load DAC control input (active low). When LDAC is low, the DAC latch is simultaneously updated with the content 15 LDAC of the input register. 16 DGND Digital ground 5 Submit Documentation Feedback |
