configured in unipolar or bipolar modes of operation
(Figures 1 and 3). These are the changes the op amp can
cause to the INL, DNL, unipolar offset, unipolar gain error,
bipolar zero and bipolar gain error. Table 4 contains a
partial list of LTC precision op amps recommended for use
with the LTC1599. The two sets of easy-to-use design
equations simplify the selection of op amps to meet the
system’s specified error budget. Select the amplifier from
Table 4 and insert the specified op amp parameters in
either Table 2 or Table 3. Add up all the errors for each
category to determine the effect the op amp has on the
accuracy of the LTC1599. Arithmetic summation gives an
(unlikely) worst-case effect. RMS summation produces a
more realistic effect.
Op amp offset will contribute mostly to output offset and
gain error and has minimal effect on INL and DNL. For the
LTC1599, a 500V op amp offset will cause about 0.55LSB
INL degradation and 0.15LSB DNL degradation with a 10V
full-scale range (20V range in bipolar). For the LTC1599
configured in the unipolar mode, the same 500V op amp
offset will cause a 3.3LSB zero-scale error and a 3.45LSB
gain error with a 10V full-scale range.
While not directly addressed by the simple equations in
Tables 2 and 3, temperature effects can be handled just as
easily for unipolar and bipolar applications. First, consult
an op amp’s data sheet to find the worst-case VOS and IB
over temperature. Then, plug these numbers in the VOS
and IB equations from Table 2 or Table 3 and calculate the
temperature induced effects.
For applications where fast settling time is important,
Application Note 74, entitled “
Component and Measure-
ment Advances Ensure 16-Bit DAC Settling Time,” offers
a thorough discussion of 16-bit DAC settling time and op
amp selection.
