Typical Applications (continued)
Passive: Resistor matching for the op-amp resistor network is critical for the success of this design and
components should be chosen with tight tolerances. For this design 0.1% resistor values are implemented but
this constraint may be adjusted based on application-specific design goals. Resistor matching contributes to both
offset error and gain error in this design; see the TI Precision Design TIPD125, Bipolar ±10V Analog Output from
a Unipolar Voltage Output DAC for further details. The tolerance of stability components RISO and CCOMP is
not critical and 1% components are acceptable.
