AD8314ARM

The AD8314ARM is one member of the AD8314 series.The AD8314 is a complete low-cost subsystem for the measurement and control of RF signals in the frequency range 0.1 GHz2.5 GHz, with a typical dynamic range of 45 dB,intended for use in a wide variety of cellular handsets and other wireless devices. It provides a wider dynamic range and better accuracy than possible using discrete diode detectors. In particular, its temperature stability is excellent over the full operating range of30 to +85.

Features of the AD8314ARM are:(1)complete RF detector/controller function; (2)typical range 58 dBV to 13 dBV45 dBm to 0 dBm re 50; (3)frequency response from 100 MHz to 2.5 GHz; (4)temperature-stable linear-in-dB response accurate to 2.5 GHz; (5)rapid response: 70 ns to a 10 dB step; (6)low power: 12 mW at 2.7 V; (7)power-down to 20 A.The AD8314 provides two voltage outputs. The first, called V_UP, increases from close to ground to about 1.2 V as the input signal level increases from 1.25 mV to 224 mV. This output is intended for use in measurement mode. Consult the Applications section of this data sheet for information on use in this mode. A capacitor may be connected between the V_UP and FLTR pins when it is desirable to increase the time interval over which averaging of the input waveform occurs.

The absolute maximum ratings of the AD8314ARM can be summarized as:(1)supply voltage VPOS:-5.5V;(2)storage temperature range:-65 to 150;(3)input voltage:1.6V;(4)operating temperature:-30 to 85;(5)internal power dissipation:200mW.Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection.Although the AD8314 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
