15 / 58 page DS673F2 15 CS42432 ANALOG INPUT CHARACTERISTICS (AUTOMOTIVE) (Test Conditions (unless otherwise specified): TA = -40 to +85°C; VD = VLS = VLC = 3.3 V±5%, VA = 5 V±5%; Full-scale input sine wave: 1 kHz through the active input filter in Figure 19 on page 48 and Figure 20 on page 48; Measurement Bandwidth is 10 Hz to 20 kHz.) Notes: 5. Referred to the typical full-scale voltage. 6. Measured between AINx+ and AINx-. 7. Measured between AINxx and AGND. 8. The input impedance scales inversely proportionate to the sample rate of the ADC modulator.
