• The LM334 provides an ISET directly proportional to absolute temperature. This cancels the slight GBW product
Temperature coefficient of the LM346.

• For ISET1≃ISET2 resistors R1 and R2 are not required if a slight error between the 2 set currents can be tolerated. If
not, then use R1 = R2 to create a 100 mV drop across these resistors.
