11 / 66 page  PCM3168A www.ti.com SBAS452A – SEPTEMBER 2008 – REVISED JANUARY 2016 Electrical Characteristics (continued) At TA = 25°C, VCCAD1 = VCCAD2 = VCCDA1 = VCCDA2 = 5 V, VDD1 = VDD2 = 3.3 V, fS = 48 kHz, SCKI = 512 fS, 24-bit data, Sampling Mode = Auto for ADC and DAC, and Interface Mode = Slave for ADC and DAC, unless otherwise noted. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT DYNAMIC PERFORMANCE(9)(10) fS = 48 kHz –94 –88 THD+N, VOUT = 0 dB fS = 96 kHz –94 dB fS = 192 kHz –94 fS = 48 kHz, EIAJ, A- 105 112 weighted fS = 96 kHz, EIAJ, A- Dynamic range 112 dB weighted fS = 192 kHz, EIAJ, A- 112 weighted fS = 48 kHz, EIAJ, A- 105 112 weighted fS = 96 kHz, EIAJ, A- S/N ratio 112 dB weighted fS = 192 kHz, EIAJ, A- 112 weighted fS = 48 kHz 102 108 Channel separation fS = 96 kHz 108 dB (between one channel and others) fS = 192 kHz 108 ANALOG OUTPUT Output voltage Differential 1.6 × VCCDA1 VPP Center voltage 0.5 × VCCDA1 V To AC-coupled GND(11) 5 Load impedance k Ω To DC-coupled GND(11) 15 f = 20 kHz –0.04 Lowpass filter frequency response dB f = 44 kHz –0.18 DIGITAL FILTER PERFORMANCE(12) Slow roll-off Passband (single, dual) 0.454 × fS Hz Passband (quad) 0.432 × fS Hz Stop band (single, dual) 0.546 × fS Hz Stop band (quad) 0.569 × fS Hz Passband ripple ≤ 0.454 × fS ±0.0018 dB Stop band attenuation > 0.546 × fS, 0.569 × fS –75 dB DIGITAL FILTER PERFORMANCE Slow roll-off Passband 0.328 × fS Hz Stop band 0.673 × fS Hz Passband ripple < 0.328 × fS ±0.0013 dB Stop band attenuation > 0.673 × fS –75 dB (9) In differential mode at VOUTx± pin, fOUT = 1 kHz, using Audio Precision System II, RMS mode with 20-kHz lowpass filter and 400-Hz highpass filter. (10) fS = 48 kHz : SCKI = 512 fS (single), fS = 96 kHz : SCKI = 256 fS (dual), fS = 192 kHz : SCKI = 128 fS (quad). (11) Allowable minimum input resistance of differential to single-ended converter with D to S Gain = G is calculated as (1 + 2G)/(1 + G) × 5k for AC-coupled and (1+ 0.9G)/(1 + G) × 15k for DC-coupled connection, refer to Figure 61 and Figure 62 of the Application Information section. (12) Exclude single and dual at 128 fS, 192 fS system clock and quad at 256 fS to 768 fS system clock, and specifications for quad, single, and dual are respectively applied in reverse for them.
