308MHz/315MHz/418MHz/433.92MHz
Low-Power, FSK Superheterodyne Receiver
DC ELECTRICAL CHARACTERISTICS (continued)
(Typical Application Circuit, 50 ? system impedance, V AVDD = V DVDD = V HVIN = +2.4V to +3.6V, f RF = 308, 315, 418, and
433.92MHz; T A = -40°C to +125°C, unless otherwise noted. Typical values are at V AVDD = V DVDD = V HVIN = +3.0V,
f RF = 433.92MHz, P RFIN ≤ -80dBm, T A = +25°C, unless otherwise noted.)
