interference rejection ratio(3)

Vin = -10 dBm, f = 400 MHz

Vin = -10 dBm, f = 900 MHz

Vin = -10 dBm, f = 1.8 GHz

Vin = -10 dBm, f = 2.4 GHz

Typical value is based on the V

io drift observed after 1000h at 125 °C extrapolated to 25 °C using the Arrhenius law and

assuming an activation energy of 0.7 eV. The operational amplifier is aged in follower mode configuration.

Guaranteed by design.

Based on evaluations performed only in conductive mode.
