FEATURES
DESCRIPTION
● SAMPLING FREQUENCY (fS): 16kHz to 96kHz
The PCM1704 is a precision, 24-bit digital-to-analog
converter with exceptionally high dynamic perfor-
mance. The ultra-low distortion and excellent low-
level signal performance makes the PCM1704 an ideal
candidate for high-end consumer and professional
audio applications. When used with a digital interpo-
lation filter, the PCM1704 supports 8X oversampling
at 96kHz.
● 8X OVERSAMPLING AT 96kHz
● INPUT AUDIO DATA WORD: 20-, 24-Bit
● HIGH PERFORMANCE:
Dynamic Range: K Grade = 112dB typ
SNR: 120dB typ
THD+N: K Grade = 0.0008% typ
● FAST CURRENT OUTPUT: ±1.2mA/200ns
● GLITCH-FREE OUTPUT
The PCM1704 incorporates a BiCMOS sign-magni-
tude architecture that eliminates glitches and other
nonlinearities around bipolar zero. The PCM1704 is
precision laser-trimmed at the factory to minimize
differential linearity and gain errors.
● PIN-PROGRAMMABLE DATA INVERSION
● POWER SUPPLY: ±5V
● SMALL 20-LEAD SO PACKAGE
In addition to high performance audio systems, the
PCM1704 is well-suited to waveform synthesis appli-
cations requiring very low distortion and noise.
