Bipolar (4-Quadrant Multiplying) Mode
(VOUT = –VREF to VREF)
The LTC1595/LTC1596 can be used with a dual op amp
and three external resistors to provide 4-quadrant multi-
plying operation as shown in Figure 2 (last page). With a
fixed 10V reference, the circuits shown give a precision
bipolar –10V to 10V output swing. Using the LTC1596-1
will cause the power-on reset and clear pin to reset the
DAC to mid-scale (bipolar zero).
Op Amp Selection
Because of the extremely high accuracy of the 16-bit
LTC1595/LTC1596, thought should be given to op amp
selection in order to achieve the exceptional performance
of which the part is capable. Fortunately, the sensitivity of
INL and DNL to op amp offset has been greatly reduced
compared to previous generations of multiplying DACs.
Op amp offset will contribute mostly to output offset and
gain and will have minimal effect on INL and DNL. For
example, a 500V op amp offset will cause about 0.55LSB
INL degradation and 0.15LSB DNL degradation with a 10V
full-scale range. The main effects of op amp offset will
be a degradation of zero-scale error equal to the op amp
offset, and a degradation of full-scale error equal to twice
the op amp offset. For example, the same 500V op amp
offset will cause a 3.3LSB zero-scale error and a 6.5LSB
full-scale error with a 10V full-scale range.
Op amp input bias current (IBIAS) contributes only a zero-
scale error equal to IBIAS(RFB) = IBIAS(RREF) = IBIAS(7k).
Table 2 shows a selection of LTC op amps which are
suitable for use with the LTC1595/LTC1596. For a thor-
ough discussion of 16-bit DAC settling time and op amp
selection, refer to Application Note 74, “Component and
MeasurementAdvancesEnsure16-BitDACSettlingTime.”
Grounding
As with any high resolution converter, clean grounding
is important. A low impedance analog ground plane and
star grounding should be used. IOUT2 (LTC1596) and GND
(LTC1595) must be tied to the star ground with as low a
resistance as possible.
