Description
DAC Reference Input in Two-Quadrant Mode and R2 Terminal in Four-Quadrant Mode. In two-quadrant mode, this
pin is the reference input with constant input resistance vs. code. In four-quadrant mode, this pin is driven by the
external reference amplifier.
DAC Current Output. Connects to the inverting node of an external op amp for I-V conversion.
Digital Input Load DAC Control. The signal level must be ≤ V
Write Control Digital Input in Active Low. Transfers shift-register data to the DAC register on the rising edge. The
signal level must be ≤ V
Power On Reset State. MSB = 0 resets at zero scale; MSB = 1 resets at midscale. The signal level must be
≤ V
Reset in Active Low. Resets to zero scale if MSB = 0 and resets to midscale if MSB = 1. The signal level must be
≤ V
Analog and Digital Grounds.
Digital Input Data Bits[D13:D6]. The signal level must be ≤ V
Positive Power Supply Input. Specified range of operation: 2.7 V to 5.5 V.
