ANALOG INPUT CHARACTERISTICS

Notes: 7. Maximum integrated noise over the measurement bandwidth for the voltage reference device attached

to the VREF± inputs.

8. Anti-alias capacitors are discrete external components and must be of good quality (C0G, NPO, poly).

Poor quality capacitors will degrade total harmonic distortion (THD) performance. See Figure 1 on
