4 / 36 page CS4227 4 DS281PP2 1. CHARACTERISTICS AND SPECIFICATIONS ANALOG CHARACTERISTICS (T A = 25 °C; VA+, VD+ = +5 V; Full Scale Input Sine wave, 997 kHz; Fs = 44.1 kHz; Measurement Bandwidth is 20 Hz to 20 kHz; Local components as shown in Figure 5; SPI mode, Format 3, unless otherwise specified.) Notes: 1. Referenced to typical full-scale differential input voltage (2Vrms). 2. Input resistance is for the input selected. Non-selected inputs have a very high (>1M Ω) input resistance. The input resistance will vary with gain value selected, but will always be greater than the min. value specified. 3. Filter characteristics scale with output sample rate. 4. The analog modulator samples the input at 5.6448 MHz for an output sample rate of 44.1 kHz. There is no rejection of input signals which are multiples of the sampling frequency (n x 5.6448 MHz ±20.0 kHz where n = 0,1,2,3...). 5. Group delay for Fs = 44.1 kHz, tgd = 15/44.1 kHz = 340 µs Parameter Symbol CS4227-KQ CS4227-BQ Units Min Typ Max Min Typ Max Analog Input Characteristics - Minimum gain setting (0 dB) Differential Input; unless otherwise specified.
