9 / 50 page DS618F2 9 CS4382A DAC ANALOG CHARACTERISTICS - COMMERCIAL (-CQZ) Test Conditions (unless otherwise specified): VA = VLS = VLC = 5 V; VD = 2.5 V; TA = 25°C; Full-Scale 997 Hz input sine wave (Note 1); Tested under max ac-load resistance; Valid with FILT+ and VQ capacitors as shown in “Typical Connection Diagram” on page 19; Measurement Bandwidth 10 Hz to 20 kHz. Notes: 1. One-half LSB of triangular PDF dither is added to data. 2. Performance limited by 16-bit quantization noise. 3. VFS is tested under load RL and includes attenuation due to ZOUT Parameters Symbol Min Typ Max Unit FS = 48 kHz, 96 kHz, 192 kHz and DSD Dynamic Range 24-bit A-weighted Unweighted 16-bit A-weighted (Note 2) Unweighted 108 105 - - 114 111 97 94 - - - - dB dB dB dB Total Harmonic Distortion + Noise 24-bit 0 dB -20 dB -60 dB (Note 2) 16-bit 0 dB -20 dB -60 dB THD+N - - - - - - -100 -91 -51 -94 -74 -34 -94 - -45 - - - dB dB dB dB dB dB Idle Channel Noise / Signal-to-noise Ratio - 114 - dB Interchannel Isolation (1 kHz) - 110 - dB DC Accuracy Interchannel Gain Mismatch - 0.1 - dB Gain Drift - 100 - ppm/°C Analog Output Full-scale Differential Output Voltage VFS 128%•VA 132%•VA 136%•VA Vpp Output Impedance (Note 3) ZOUT -130 - Ω Max DC Current Draw From an AOUT Pin IOUTmax -1.0 - mA Min AC-load Resistance RL -3 - k Ω Max Load Capacitance CL -100 - pF Quiescent Voltage VQ - 50%•VA -VDC Max Current draw from VQ IQMAX -10 - µA |
