Figure 32. Typical Application for Analog Output Stage
Analog Output Level and LPF
The signal level of the DAC differential-voltage output {(VOUTL+)–(VOUTL–), (VOUTR+)–(VOUTR–)} is 3.2 V p-p
at 0 dB (full scale). The voltage output of the LPF is given by following equation:
VOUT = 3.2 V p-p × (Rf/Ri)
Here, Rf is the feedback resistor in the LPF, and R3 = R4 in a typical application circuit. Ri is the input resistor
in the LPF, and R1 = R2 in a typical application circuit.
Op Amp for LPF
An OPA2134 or 5532 type op amp is recommended for the LPF circuit to obtain the specified audio
performance. Dynamic performance such as gain bandwidth, settling time, and slew rate of the op amp largely
determines the audio dynamic performance of the LPF section. The input noise specification of the op amp
should be considered to obtain a 113-dB S/N ratio.
