43 / 79 page  TAS3208 www.ti.com SLES201E – JANUARY 2007 – REVISED MARCH 2011 ELECTRICAL SPECIFICATIONS – ANALOG SECTIONS (1) TA = 25°C, AVDD = 3.3 V, DVDD = 3.3 V, Fs (audio) = 48 kHz, clock source from XTALI, AES17 filter, second-order 30-kHz low-pass filter (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT Stereo MUX Input/ADC Channel 1-kHz sine-wave input Full-scale input voltage (0 dB) 1 1.15 Vrms Input common-mode voltage Over recommended operating conditions 1.43 1.5 1.57 V DNR –60-dB full-scale input applied at line inputs, A-weighted 90 93 dBA THD + N 1-kHz, –4-dB full-scale input –75 –80 dB PSRR 1 kHz, 100 mVpp on AVDD 51 57 dB Channel separation 1 kHz –80 –90 dB Input resistance 14.6 18.33 22 k Ω Input capacitance 10 pF DAC Channel/DAC Output 1-kHz sine-wave input, Load = 10 k Ω, 10 pF Full-scale output voltage (0 dB) 0.81 0.9 Vrms Gain error –10 10 % Output common mode Over recommended operating conditions 1.43 1.5 1.57 V DNR –60-dB full-scale input applied at line inputs, A-weighted 95 97 dBA THD + N –1-dBFS input, 0-dB gain –80 –90 dB PSRR 1 kHz, 100 mVpp on AVDD, VGND powered down 50 56 dB Load capacitance pF Load resistance 10 k Ω Channel separation –81 –84 dB 1-kHz sine-wave input, Load = 16 Ω, DAC Channel/ Headphone Output External series resistance = 16 Ω, Coupling capacitance = 47 µF Full-scale output voltage (0 dB) 0.72 0.9 Vrms DNR –60-dB full-scale input applied at Line inputs, A-weighted 80 90 dBA THD + N 0-dBFS input, 0-dB gain –50 –60 dB PSRR 1 kHz, 100 mVpp on AVDD , VGND powered down 48 54 dB Maximum output power(2) 24 mW Load capacitance 100 pF Load resistance 16 Ω Channel separation –70 –80 dB (1) When the TAS3208 is operated in slave mode, the internal analog clocks for ADC and DAC are derived from external MCLKIN input. In this case, the analog performance will depend on MCLKIN quality (i.e., jitter, phase noise, etc.). (2) 16- Ω series resistor required in L and R headphone outputs for short-circuit protection.
