6 / 16 page  6 LTC1664 PIN FUNCTIONS GND (Pin 1): System Ground. VOUT A to VOUT D (Pins 2–5): DAC Analog Voltage Outputs. The output range is 0 1023 1024 to VREF REF (Pin 6): Reference Voltage Input. 0V ≤ VREF ≤ VCC. CS/LD (Pin 7): Serial Interface Chip Select/Load Input. When CS/LD is low, SCK is enabled for shifting data on DIN into the register. When CS/LD is pulled high, SCK is disabled and data is loaded from the shift register into the specified DAC register(s), updating the analog output(s). CMOS and TTL compatible. SCK (Pin 8): Serial Interface Clock Input. CMOS and TTL compatible. DIN (Pin 9): Serial Interface Data Input. Data on the DIN pin is shifted into the 16-bit register on the rising edge of SCK. CMOS and TTL compatible. DOUT (Pin 10): Serial Interface Data Output. Data appears on DOUT 16 positive SCK edges after being applied to DIN. May be tied to DIN of another serial device for daisy-chain operaton. CMOS and TTL compatible. CLR (Pin 11): Asynchronous Clear Input. All internal shift and DAC registers are cleared to zero at the falling edge of the CLR signal, forcing the analog outputs to zero scale. CMOS and TTL compatible. NC (Pins 12–15): Make no electrical connection to these pins. VCC (Pin 16): Supply Voltage Input. 2.7V ≤ VCC ≤ 5.5V. |
