LINE REGULATION
Line regulation is a measure of change in output voltage due to
a specified change in input voltage. It is intended to simulate
worst-case unregulated supply conditions and is measured in
μV/V. Figure 20 shows typical performance with 4.0 V < V IN <
15.0 V.

Figure 17. Settling under Transient Resistive Load
The dynamic load may be resistive and capacitive. For example,
and Figure 19 show the performance of the AD780 driving a
1000 pF, 0 mA to 10 mA load.

capacitive load, has superior dynamic load performance, and its

3.0 V output provides the converter with the maximum
dynamic range without requiring an additional and expensive
buffer amplifier. One of the many ADCs that the AD780 is
suited for is the AD7884, a 16-bit, high speed sampling ADC
(see Figure 21). This part previously needed a precision 5 V
reference, resistor divider, and buffer amplifier to do this
function.
