DAC ANALOG CHARACTERISTICS
Test Conditions (unless otherwise indicated): 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
“Typical Connection Diagram” on page 18; Measurement Bandwidth 10 Hz to 20 kHz.
Notes:
1. One-half LSB of triangular PDF dither is added to data.
2. Performance limited by 16-bit quantization noise.
3. V
