SLAS411D November 2004 – February 2016 DAC8811
PRODUCTION DATA.
PIN | TYPE | DESCRIPTION | |
---|---|---|---|
NAME | NO. | ||
CLK | 1 | I | Clock input; positive edge triggered clocks data into shift register |
SDI | 2 | I | Serial register input; data loads directly into the shift register MSB first. Extra leading bits are ignored. |
RFB | 3 | O | Internal matching feedback resistor. Connect to external op amp output. |
VREF | 4 | I | DAC reference input pin. Establishes DAC full-scale voltage. Constant input resistance versus code. |
IOUT | 5 | O | DAC current output. Connects to inverting terminal of external precision I/V op amp. |
GND | 6 | G | Analog and digital ground. |
VDD | 7 | I | Positive power supply input. Specified operating range of 2.7 V to 5.5 V. |
CS | 8 | I | Chip-select; active low digital input. Transfers shift register data to DAC register on rising edge. See Table 1 for operation. |
