= 25°C; VA = +5V, VD = VL = +3.3V;
Full Scale Input Sine wave, 1kHz; Fs = 44.1 kHz BRM, 96 kHz HRM; Measurement Bandwidth is 20 Hz to 20 kHz;
Local components as shown in "Recommended Connection Diagram"; SPI control mode, Left Justified serial for-
mat, MCLK = 256 Fs BRM, 128 Fs HRM, SCLK = 64 Fs)
Notes: 1.
Referenced to typical full-scale differential input voltage (2 Vrms).
Filter characteristics scale with output sample rate.
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 × 5.6448 MHz ±20.0 kHz
where n = 0,1,2,3...).
Group delay for Fs = 44.1 kHz, t
gd
= 15/44.1 kHz = 340
