Test conditions (unless otherwise specified): T

A

= -40°C to 85°C, VA_H = 9 V, VA = 3.3 V, VD = 3.3 V GND = 0 V;

VBIAS+ and VQ capacitors as shown in

Figure 2 on page 10

; input test signal is a 997 Hz sine wave at 0 dBFS;

measurement bandwidth 10 Hz to 20 kHz.

Notes:

2.

One-half LSB of triangular PDF dither is added to data.
