◦
C, XTALI=12 MHz,
Internal Clock Multiplier 3.0×. DAC tested with full-scale output sinewave, measurement bandwidth
20..20000 Hz, analog output load: LEFT to CBUF 30 Ω, RIGHT to CBUF 30 Ω.
Parameter Symbol Min Typ Max Unit

Total harmonic distortion, max level, no load THD 0.01 %
Total harmonic distortion, max level, 30 ohm load THDL 0.1 0.3 %
Crosstalk (L/R to R/L), 30 ohm load, without CBUF
1
XTALK1 75 dB
Crosstalk (L/R to R/L), 30 ohm load, with CBUF XTALK2 54 dB
Gain mismatch (L/R to R/L) GERR -0.5 0.5 dB
Frequency response AERR -0.05 0.05 dB

pF
DC level (CBUF, LEFT, RIGHT) 1.1 1.3 V
CBUF disconnect current (short-circuit protection) 130 200 mA
1
Loaded from Left/Right pin to analog ground via 100 µF capacitors.
2
AOLR may be lower than Typical, but distortion performance may be compromised. Also,
there is a maximum current that the internal regulators can provide.
3
CBUF must have external 10 Ω + 47 nF load, LEFT and RIGHT must have external 20 Ω +
10 nF load for optimum stability and ESD tolerance.
