DAC ANALOG CHARACTERISTICS - COMMERCIAL (-CQZ)

Test Conditions (unless otherwise specified): VA = VLS = VLC = 5 V; VD = 2.5 V; T

A

= 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 19

; 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.
