... The DAC16 was designed to operate with an operational amplifier configured as an I–V converter; therefore, the DAC16’s output must be connected to the sum node of an operational amplifier for proper operation. Exceeding the output voltage compliance of the DAC16 will introduce linearity errors. ...

... Digital Input Considerations The threshold of the DAC16’s digital input circuitry is set at 1.4 V, independent of supply voltage. Hence, the digital inputs can interface with any type logic. Illustrated in Figure 5 is the equivalent circuit of the digital inputs. Note that the indi- vidual input capacitance is approximately 7 pF. ...

... AD843 offer the requisite settling time. Although these amplifi- ers are not specified for 16-bit performance, their settling times are two to three times faster than the DAC16 and will introduce negligible error to the overall circuit’s settling time possible to estimate the 16-bit settling time of an operational amplifier if its 12-bit settling time is known ...

... DAC16 In using high speed op amps, the output capacitance of the DAC16 appears across the inputs of the op amp where it and the op amp’s input capacitance will set an additional pole in the op amp’s loop gain response. The pole is formed with the feedback resistance and the output resistance of the DAC. This additional pole may adversely affect the transient response of the circuit due to the added phase shift ...
