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
; 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.
