Terminal Voltage Range – Voltage range over which product functions as a potentiometer divider. Terminal Voltage Range for these parts extends from the Negative Supply (or Ground) to V_refH. Check individual parts for minimum operating voltage,usually 2.7V. Some parts have a head room restriction on maximum Out voltage.
Supply (Idd) – Supply Current consumption
Interface Data Control – 3-wire interface is SPI & µWire compatible
Nominal Resistance – Unbuffered DAC Out resistance
Resolution – Number of bits,produces 2^N Out voltages
Internal Power ON Reset. These parts have an internal power ON reset
Most devices contain an external RS pin that asynchronously forces the Out to zero or midscale code
TrimDACs are used to replace Potentiometers in new designs where the Potentiometer was used in the voltage divider mode driving a high impedance node for adjustment. One important variation of the TrimDAC series is the 4-Quadrant multiplying devices designed for AC signal level adjustment.
