Description
The CS4391A is a complete stereo digital-to-analog sys-
tem including digital interpolation, fourth-order delta-
sigma digital-to-analog conversion, digital de-emphasis,
volume control, channel mixing and analog filtering. The
advantages of this architecture include: ideal differential
linearity, no distortion mechanisms due to resistor
matching errors, no linearity drift over time and tempera-
ture and a high tolerance to clock jitter.
The CS4391A accepts PCM data at sample rates from
4 kHz to 192 kHz, DSD audio data, consumes very little
power and operates over a wide power supply range.
These features are ideal for DVD, A/V receivers, CD and
set-top box systems.

Notes: 1. Triangular PDF dithered data.
2. THD+N specifications for 48 kHz sample rates are made over a 20 kHz Bandwidth.
3. Valid with the recommended capacitor values on FILT+ and CMOUT as shown in Figure 1. Increasing
the capacitance will also increase the PSRR.
4. Response is clock dependent and will scale with Fs. Note that the response plots (Figures 18-25) have
been normalized to Fs and can be de-normalized by multiplying the X-axis scale by Fs.
5. For Single-Speed Mode, the Measurement Bandwidth is 0.5465 Fs to 3 Fs.
For Double-Speed Mode, the Measurement Bandwidth is 0.577 Fs to 1.4 Fs.
