Figure 50. Quad DAC Unipolar Operation
FAST I-TO-V CONVERTER
The fast slew rate and fast settling time of the OP467 are well
suited to the fast buffers and I-to-V converters used in a variety
of applications. The circuit in Figure 50 is a unipolar quad DAC
consisting of only two ICs. The current output of the DAC8408
is converted to a voltage by the OP467 configured as an I-to-V
converter. This circuit is capable of settling to 0.1% within 200 ns.
outputs. To obtain reliable circuit performance, keep the traces
from the IOUT of the DAC to the inverting inputs of the OP467
short to minimize parasitic capacitance.
