1. CHARACTERISTICS AND SPECIFICATIONS
ANALOG CHARACTERISTICS
(T
A
= 25° C; VA, VD = +5 V; Full Scale Input Sine wave, 997 Hz;
Fs = 48 kHz; Measurement Bandwidth is 20 Hz to 20 kHz; Local components as shown in Figures 4 and 5; SPI
mode, Format 0, unless otherwise specified.)
Notes: 1.
Referenced to typical full-scale differential input voltage (2 Vrms).
Filter characteristics scale with output sample rate. For output sample rates, Fs, other than 48 kHz, the
0.01 dB passband edge is 0.4535x Fs and the stopband edge is 0.625x Fs.
The analog modulator samples the input at 6.144 MHz for an Fs equal to 48 kHz. There is no rejection
of input signals which are multiples of the sampling frequency (n x 6.144 MHz ±21.8 kHz where
n = 0,1,2,3...).
Group delay for Fs = 48 kHz, t
gd
= 15/48 kHz = 312 μs.
