DESCRIPTION
I/O Data input/output, (pin 1-MSB: pin 16-LSB)
I Digital ground
I Digital supply input, 1.8 V to 5.5 V
I Analog power supply input, 2.7 V to 5.5 V
I Positive reference voltage input (referenced to AGND)
I Negative reference voltage input (referenced to AGND), nominally VREFL = AGND
I Analog ground
I Analog output sense. The feedback terminal of the output amplifier.
O Analog output voltage from DAC. The output amplifier has rail-to-rail operation.
I Powerdown control bit 0
I Powerdown control bit 1
I Data input format: binary twos complement or unipolar straight binary
I Reset VOUT on active RST to min-scale (RSTSEL = 0) or mid-scale (RSTSEL = 1)
I VOUT reset to min-scale or mid-scale, rising edge (Does not reset input register data.)
I Asynchronous load command, rising edge
I Read/Write control input
I Chip select, active low
