DAC ANALOG CHARACTERISTICS (AUTOMOTIVE - DNZ)
Test conditions (unless otherwise specified): TA = -40 to +85 °C; VCP = VA = 3.13 V to 3.47 V; AOUT_REF =
AGND = DGND = CPGND = 0 V; VBIAS, +/-VFILT, and FLYP/N+/- capacitors as shown in Figure 3 on page 13;
input test signal is a 997 Hz sine wave at 0 dBFS; measurement bandwidth 10 Hz to 20 kHz.
1_2VRMS = 0
1_2VRMS = 1
