(1) Dynamic performance and DC accuracy are specified at the output of the postamplifier as shown in Figure 28. Analog performance specifications

are measured using the System Two

t Cascade audio measurement system by Audio Precisiont in the averaging mode. At all sampling

frequency operations, measurement bandwidth is limited with a 20-kHz AES17 filter.

(2) These parameters are defined at the PCM1793 output pin. Load impedance, R1 and R2, are input resistors of the postamplifier. These are defined

as dc loads.
