DAC ANALOG CHARACTERISTICS - COMMERCIAL (-CQZ)
Test Conditions (unless otherwise specified): VA = VLS = VLC = 5 V; VD = 2.5 V; TA = 25°C; Full-Scale 997 Hz
input sine wave
(Note 1); Tested under max ac-load resistance; Valid with FILT+ and VQ capacitors as shown in
Notes:
1.
One-half LSB of triangular PDF dither is added to data.
2.
Performance limited by 16-bit quantization noise.
3.
VFS is tested under load RL and includes attenuation due to ZOUT
