1. CHARACTERISTICS AND SPECIFICATIONS

ADC CHARACTERISTICS (T

A = 25° C; VA, VD = + 5 V; -1 dB Full Scale Input Sine wave, 997 Hz; Fs =

48 kHz; XTI = 12.2880 MHz; Measurement Bandwidth is 20 Hz to 20 kHz)

Notes: 1. Referenced to typical full-scale differential input voltage (2 Vrms).

2. Bench tested only.

3. Filter characteristics scale with output sample rate.

4. Measured using differential analog input circuit, see Figure 6.

5. Filter response is not tested but is guaranteed by design.
