6 / 15 page WM8738 Production Data w PD Rev 4.3 November 2004 6 ELECTRICAL CHARACTERISTICS Test Conditions AVDD = 5.0V, AGND = 0V, DVDD = 3.3V, DGND = 0V, TA = +25 oC, fs = 48kHz, MCLK = 256fs unless otherwise stated. PARAMETER SYMBOL TEST CONDITIONS MIN TYP MAX UNIT Digital Logic Levels (TTL Levels) Input LOW level VIL 0.8 V Input HIGH level VIH 2.0 V Output LOW VOL IOL = 1mA 0.1 x DVDD V Output HIGH VOH IOH = 1mA 0.9 x DVDD V Pull down resistance (FMT, NOHP) RPD 100 k Ω Analogue Reference Levels Reference voltage VCAP AVDD/2 – 50mV AVDD/2 AVDD/2 + 50mV V Buffered reference voltage VREF VCAP V Potential divider output impedance RCAP 40 50 60 k Ω Input to ADC Input Signal Level (0dB) VRIN / VLIN 1.0 Vrms SNR (Note 1,2) A-weighted, 0dB gain @ fs = 48KHz 90 dB SNR (Note 1,2) A-weighted, 0dB gain @ fs = 96KHz 90 dB SNR (Note 1,2) A-weighted, 0dB gain @ fs = 48KHz, AVDD = 3.3V 90 dB Dynamic Range (Note 2) DNR A-weighted, -60dB full scale input 90 97 dB Total Harmonic Distortion (THD) (Note 4) -1dB input, 0dB gain -87 dB ADC channel separation 1KHz input 95 dB 1kHz 100mVp-p 50 dB Power Supply Rejection Ratio PSRR 20Hz to 20kHz 100mVp-p 45 dB Input Resistance 20 k Ω Input Capacitance 10 pF Notes 1. Ratio of output level with 1kHz full scale input, to the output level with the input open circuited, measured ‘A’ weighted over a 20Hz to 20kHz bandwidth using an Audio analyser. 2. All performance measurements done with 20kHz low pass filter, and where noted an A-weight filter. Failure to use such a filter will result in higher THD+N and lower SNR and Dynamic Range readings than are found in the Electrical Characteristics. The low pass filter removes out of band noise; although it is not audible it may affect dynamic specification values. 3. VREF and CAP de-coupled with 10uF and 0.1uF capacitors (smaller values may result in reduced performance). 4. This data is measured, using an active filter on the device inputs. |
