ASK/FSK Superheterodyne Receiver
DC ELECTRICAL CHARACTERISTICS (continued)
(Typical Application Circuit, AV_DD = DV_DD = HV_IN = +2.4V to +3.6V, f_RF = 300MHz to 450MHz, T_A = -40°C to +125°C, unless otherwise
noted. Typical values are at AV_DD = DV_DD = HV_IN = +3.0V, f_RF = 434 MHz, T_A = +25°C, unless otherwise noted.) (Note 1)
