3 Characteristics and Specifications

13. 5.2/Fs for 32-kHz sample rate.

14. 3.9 dB for 32-kHz sample rate (passband droop 10 Hz to 15 kHz).

Table 3-9. DAC High-Pass Filter (HPF) Characteristics

Test conditions (unless specified otherwise): Gains are all set to 0 dB; TA = +25°C.

Parameter 1

1.Response scales with Fs in PCM Mode. Specifications are normalized to Fs and are denormalized by multiplying by Fs. For DSD Mode, Fs is 44.1 kHz.

Table 3-10. DSD Combined Digital and On-Chip Analog Filter Response 1

Test conditions (unless specified otherwise): Digital gains are all set to 0 dB; TA = +25°C; PDN_XTAL = 0, MCLK_INT = 1, and MCLK_SRC_SEL = 00

(crystal frequency fXTAL = 22.5792 MHz).

1.Filter response is by design.
