=
Electrical Characteristics are over recommended operating conditions unless otherwise stated
Typical figure are at 25
°
C with nominal ±5V supplies and are for design aid only
*All test conditions use a test source impedance which matches the device’s input impedance
dBm is referenced to 600
unless otherwise stated
Notes: Impedance set by external network equal to 10 times the required input impedance
Test conditions use a transmit and receive gain set to 0dB default
"Net" indicates network balance impedance
