Figure 8a. Schem atic Using False Ground

T he T HD+N figure of an audio DAC represents the amount of

undesirable signal produced during reconstruction and play-

back of an audio waveform. T herefore, the T HD+N specifica-

tion provides a direct measure to classify and choose an audio

DAC for a desired level of performance. Figure 1 illustrates the

typical T HD+N versus frequency performance of the AD1866.

It is evident that the T HD+N performance of the AD1866 re-

mains stable at all three amplitude levels through a wide range

of frequencies. A load impedance of at least 2 kΩ is recom-

mended for best T HD+N performance.

Figure 8a illustrates the traditional approach used to generate

false ground voltages in single supply audio systems. T his cir-

cuit requires additional power and circuit board space.

T he AD1866 eliminates the need for “false ground” circuitry.

V_BR and V_BL generate the required bias voltages previously

generated by the “false ground.” As shown in Figure 8b, V_BR

and V_BL may be used as the reference point in each output

channel. T his permits a dc coupled output signal path. T his

eliminates ac coupling capacitors and improves low frequency

performance. It should be noted that these bias outputs have

relatively high output impedance and will not drive output cur-

rents larger than 100 µA without degrading the specified

performance.

Analog Devices tests all AD1866s on the basis of T HD+N per-

formance. During the distortion test, a high speed digital pat-

tern generator transmits digital data to each channel of the

device under test. Sixteen-bit data is latched into the DAC at

352.8 kHz (8 × F_S). T he test input code is a digitally encoded

990.5 Hz sine wave with 0 dB, –20 dB, and –60 dB amplitudes.

A 4096 point FFT calculates total harmonic distortion + noise,

signal-to-noise ratio, and D-range. No deglitchers or external

adjustments are used.
