6.11 Audio DAC (CS4334)

CS4334 is a 8-pin, 24-bit, 96KHz stereo D/A converter. The CS4334 family is based on

Delta-Sigma modulation, where the modulator output controls the reference voltage input to an

ultra-linear analog lowpass filter. This architecture allows for infinite adjustment of sample rate between

2 kHz and 100 kHz simply by changing the master clock frequency.

The main features of CS4334 are:

• Complete stereo DAC system: interpolation, D/A, output analog filtering

• 24-bit conversion

• 96dB dynamic range

• -88dB THD+N

• Low clock jitter sensitivity

• Single +5V power supply

• Filtered line level outputs

• On-chip digital de-emphasis

• Popguard
