4 / 18 page  ® 4 DAC7614 PIN CONFIGURATION—P, U Packages Top View PDIP, SOIC PIN DESCRIPTIONS—P, U Packages PIN LABEL DESCRIPTION 1VDD Positive Analog Supply Voltage, +5V nominal. 2VOUTD DAC D Voltage Output 3VOUTC DAC C Voltage Output 4VREFL Reference Input Voltage Low. Sets minimum out- put voltage for all DACs. 5VREFH Reference Input Voltage High. Sets maximum out- put voltage for all DACs. 6VOUTB DAC B Voltage Output 7VOUTA DAC A Voltage Output 8VSS Negative Analog Supply Voltage, 0V or –5V nomi- nal. 9 GND Ground 10 SDI Serial Data Input 11 CLK Serial Data Clock 12 CS Chip Select Input 13 NIC Not Internally Connected. 14 LOADDACS The selected DAC register becomes transparent when LOADDACS is LOW. It is in the latched state when LOADDACS is HIGH. 15 RESET Asynchronous Reset Input. Sets all DAC registers to either zero-scale (000H) or mid-scale (800H) when LOW. RESETSEL determines which code is active. 16 RESETSEL When LOW, a LOW on RESET will cause all DAC registers to be set to code 000H. When RESETSEL is HIGH, a LOW on RESET will set the registers to code 800H.
