All specifications -40°C to +85 °C, unless otherwise noted. DAC8811 PARAMETER CONDITIONS MIN TYP MAX UNITS Total harmonic distortion -105 dB Output spot noise voltage 12 nV/ √Hz Table 1. TERMINAL FUNCTIONS PIN NAME DESCRIPTION 1 CLK Clock input; positive edge triggered clocks data into shift register Serial register input; data loads directly into the shift register MSB first. Extra 2 SDI leading bits are ignored. 3 RFB Internal matching feedback resistor. Connect to external op amp output. DAC reference input pin. Establishes DAC full-scale voltage. Constant input 4 VREF resistance versus code. DAC current output. Connects to inverting terminal of external precision I/V op 5 IOUT amp. 6 GND Analog and digital ground. 7 VDD Positive power supply input. Specified operating range of 2.7 V to 5.5 V. Chip-select; active low digital input. Transfers shift register data to DAC register 8 CS on rising edge. See Table 2 for operation. 4 |
