CHARACTERISTICS/SPECIFICATIONS

ANALOG CHARACTERISTICS (T

A = 25°C; VA+, VD+ = +5V; Full Scale Input Sine wave,

990.52 Hz; Fs = 44.1 kHz (PLL in use); Measurement Bandwidth is 20 Hz to 20 kHz; Local components as shown

in Figure 1; 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 × 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
