OPERATION
Voltage Outputs
Each of the rail-to-rail output amplifiers contained in the
LTC1661 can typically source or sink up to 5mA (VCC=5V).
Theoutputsswingtowithinafewmillivoltsofeithersupply
whenunloadedandhaveanequivalentoutputresistanceof
85Ω (typical) when driving a load to the rails. The output
amplifiers are stable driving capacitive loads up to 1000pF.
A small resistor placed in series with the output can be
used to achieve stability for any load capacitance. A 1F
load can be successfully driven by inserting a 20Ω resis-
tor in series with the VOUT pin. A 2.2F load needs only a
10Ω resistor, and a 10F electrolytic capacitor can be used
withoutanyresistor(theequivalentseriesresistanceofthe
capacitor itself provides the required small resistance). In
anyofthesecases,largervaluesofresistance,capacitance
or both may be substituted for the values given.
Rail-to-Rail Output Considerations
In any rail-to-rail DAC, the output swing is limited to volt-
ages within the supply range.
If the DAC offset is negative, the output for the lowest
codes limits at 0V as shown in Figure 2b.
Similarly, limiting can occur near full scale when the REF
pin is tied to VCC. If VREF = VCC and the DAC full-scale
error (FSE) is positive, the output for the highest codes
limits at VCC as shown in Figure 2c. No full-scale limiting
can occur if VREF is less than VCC – FSE.
Offset and linearity are defined and tested over the region
of the DAC transfer function where no output limiting can
occur.
