STEREO AUDIO DAC and FM CHARACTERISTICS
Unless otherwise specified, VCC = 2.7V to 3.3V, Tamb = -30°C to 85°C; typical characteristics are speci-
fied at VCC = 3V, VCMHP=1.5V, Tamb =25°C; fAMCK = 13.0MHz; Full-Scale Input Sine Waves at
1015.625Hz; Input Sample Rate (Fs) = 48kHz; Input Data = 18Bits; Measurement Bandwidth is 20Hz to
20kHz, unweighted. Resistive load on HPL, HPR = 16
).
* Valid for Audio interface input (Audio Mode).
**Calculation of TSF and SUT: we define:
k=(fAMCK
fDIV) where fAMCK is the frequency of AMCK expressed in Hz and
fDIV = 6144000(AMCK_DIV+2), where AMCK_DIV is the content of CR18, bits1-0. The approximate startup time is obtained dividing 10.6
ms by
k, and the transient suppression filter cutoff frequency is obtained multiplying 20Hz for k
Note: Fs range: 8kHz - 48kHz.
