2 / 27 page  ELECTRICAL CHARACTERISTICS PCM1800 SBAS071B – OCTOBER 2000 – REVISED AUGUST 2008 ............................................................................................................................................... www.ti.com This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. All specifications at TA = 25°C, VDD = VCC = 5 V, slave mode, fS = 44.1 kHz, 20-bit input data, and SYSCLK = 384 fS, unless otherwise noted PCM1800E PARAMETER TEST CONDITIONS UNITS MIN TYP MAX RESOLUTION 20 Bits DIGITAL INPUT/OUTPUT VIH (1) 2 Input logic level VDC VIL (1) 0.8 IIN (2) ±1 Input logic current µA IIN (3) 100 VOH (4) IOH = –1.6 mA 4.5 Output logic level VDC VOL (4) IOL = 3.2 mA 0.5 fS Sampling frequency 4 44.1 48 kHz 256 fS 1.024 11.2896 12.288 System clock frequency 384 fS 1.536 16.9344 18.432 MHz 512 fS 2.048 22.5792 24.576 DC ACCURACY Gain mismatch, channel-to-channel ±1 ±2.5 % of FSR Gain error ±2 ±5 % of FSR Gain drift ±20 ppm of FSR/°C Bipolar zero error High-pass filter bypassed ±2 % of FSR Bipolar zero drift High-pass filter bypassed ±20 ppm of FSR/°C DYNAMIC PERFORMANCE(5) THD+N at FS (–0.5 dB) –88 –80 dB THD+N at –60 dB –92 dB Dynamic range A-weighted 90 95 dB Signal-to-noise ratio A-weighted 90 95 dB Channel separation 88 93 dB DYNAMIC PERFORMANCE(5) Dynamic range 16-bit, A-weighted 94 dB Signal-to-noise ratio 16-bit, A-weighted 94 dB Channel separation 16-bit 92 dB ANALOG INPUT Input range FS (VIN = 0 dB) 2.828 Vp-p Center voltage 2.1 VDC Input impedance 30 k Ω Antialiasing filter frequency response CEXT = 470 pF, –3 dB 170 kHz DIGITAL FILTER PERFORMANCE (1) Pins 6, 7, 8, 9, 10, 11, 16 and 12, 13, 14: RSTB, BYPAS, FMT0, FMT1, MODE0, MODE1, SYSCLK, and FSYNC, LRCK, BCK in slave mode (2) Pins 16 and 12, 13, 14: SYSCLK and FSYNC, LRCK, BCK in slave mode (Schmitt-trigger input) (3) Pins 6, 7, 8, 9, 10, 11: RSTB, BYPAS, FMT0, FMT1, MODE0, MODE1 (Schmitt-trigger input, with 100-k Ω typical pulldown resistor) (4) Pins 15 and 12, 13, 14: DOUT and FSYNC, LRCK, BCK in master mode (5) fIN = 1 kHz, using the System Two™ audio measurement system by Audio Precision™, rms mode with 20-kHz LPF and 400-Hz HPF in the performance calculation. 2 Submit Documentation Feedback Copyright © 2000–2008, Texas Instruments Incorporated Product Folder Link(s): PCM1800 |
