PARAMETER SYMBOL TEST CONDITIONS MIN TYP MAX UNIT Gain mismatch Channel to channel +/-1% +/-5% % of FSR Frequency Bandwidth 0dB gain 100 kHz Master volume max gain 567 dB Master volume min gain -70 -73 -76 dB Master volume step size, codes 0 - 47 0.7 1 1.3 dB Master volume step size, codes 48 – 79 0.5 1 1.5 dB Master volume gain code 80 – 127 (mute) -90 -100 dB Mixer trim max gain 11 12 13 dB Mixer trim min gain -32.5 -34.5 -36.5 dB Mixer trim step size 1.3 1.5 1.7 dB Tone Generator SINAD (Note 3) 1Hz to 1kHz tones 65 75 dB SINAD 1kHz to 2kHz tones 60 70 dB SINAD 2kHz to 4kHz tones 55 65 dB SINAD 4kHz to 32kHz tones 50 60 dB Full scale output voltage; trims at 0dB 2.5 V pk-pk Tone Frequency TCLK frequency = 27MHz 1 32767 Hz Tone Duration TCLK frequency = 27MHz 0.1 25.5 secs Gain adjust range -46.5 0 dB Gain adjust step size (4 bit trim) 1.25 1.5 1.75 dB Notes: 1. Ratio of output level with 1kHz full scale input, to the output level with all zeros into the digital input, measured ‘A’ weighted over a 20Hz to 20kHz bandwidth. 2. All performance measurements done with 20kHz low pass 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. SINAD is ratio of signal to sum of noise, harmonics and spurii, over a bandwidth from 1Hz up to either 127x the tone frequency, or 20kHz, whichever is the lower. (This is to allow for the lower frequency tones having images at 127x and 129x the tone frequency which will fall in the audio band for tones of frequency less than about 20kHz/128). |
