CS4365
DAC ANALOG CHARACTERISTICS - AUTOMOTIVE (-DQZ)
Test Conditions (unless otherwise specified): VA = 4.75 to 5.25 V; VLS = 1.71 to 5.25 V; VLC = 1.71 to 5.25 V;
VD = 2.37 to 2.63 V; T_A = -40°C to 85°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; Measure-
ment Bandwidth 10 Hz to 20 kHz.
