Figure 46. False Ground Generator
LOW NOISE VOLTAGE REFERENCE
Few reference devices combine low noise and high output drive
capabilities. Figure 47 shows the OPx13 family used as a two-
pole active filter that band limits the noise of the 2.5 V reference.
Total noise measures 3 μV p-p.

Figure 47. Low Noise Voltage Reference
5 V ONLY STEREO DAC FOR MULTIMEDIA
The OPx13 family’s low noise and single supply capability are
ideally suited for stereo DAC audio reproduction or sound
synthesis applications such as multimedia systems. Figure 48
shows an 18-bit stereo DAC output setup that is powered from a
single 5 V supply. The low noise preserves the 18-bit dynamic
range of the AD1868. For DACs that operate on dual supplies,
the OPx13 family can also be powered from the same supplies.
