(TA = 25°C, AVDD = 1.5 V, AVSS = −1.5 V, DVDD = 3 V, DVSS = 0 V, load resistance (RL) = open, +IN = 0V, unless

otherwise noted. These default AVDD, AVSS, and +IN conditions are equivalent to a symmetrical supply

configuration with +IN biased to 0 V.)

To simplify terminology throughout this data sheet, because the two amplifiers inside the ADA4352-2 are

interchangeable, RF3, RF2, RF1, RF0, +IN, and −IN refer to Channel A or Channel B. VOUT refers to OUT A or OUT B,

within each channel, RFX refers to RF3 or RF2, RF1 or RF0, and CFX refers to CF3 or CF2, CF1 or CF0.

High speed production testing limits the accuracy of this specification.

Integrated capacitors have ±20% tolerance.
