DIGITAL PANNING CONTROL
Figure 15 uses a DAC-8408, quad 8-bit DAC to pan a signal
between two channels. The complementary DAC current out-
puts two of the DAC-8408’s four DACs drive current-to-voltage
converters built from a single quad OP470. The amplifiers have
complementary outputs with the amplitudes dependent upon
the digital code applied to the DAC. Figure 16 shows the comple-
mentary outputs for a 1 kHz input signal and digital ramp applied
to the DAC data inputs. Distortion of the digital panning con-
trol is less than 0.01%.

Figure 16. Digital Panning Control Output
Gain error due to the mismatching between the internal DAC
ladder resistors and the current-to-voltage feedback resistors is
eliminated by using feedback resistors internal to the DAC. Of
the four DACs available in the DAC-8408, only two DACs, A
and C, actually pass a signal. DACs B and D are used to pro-
vide the additional feedback resistors needed in the circuit. If
the VREFB and VREFD inputs remain unconnected, the
current-to-voltage converters using RFBB and RFBD are unaf-
fected by digital data reaching DACs B and D.
