The AD8330 is a wideband variable gain amplifier for applicationsrequiring a fully differential signal path, low noise, well-definedgain, and moderately low distortion, from dc to 150 MHz. Theinput pins can also be driven from a single-ended source. Thepeak differential input is ?2 V, allowing sine wave operation at1 V rms with generous headroom. The output pins can drivesingle-sided loads essentially rail-to-rail. The differential outputresistance is 150 ?. The output swing is a linear function of thevoltage applied to the VMAG pin that internally defaults to 0.5 V,providing a peak output of ?2 V. This can be raised to 10 V p-p,limited by the supply voltage.The basic gain function is linear-in-dB, controlled by the voltageapplied to Pin VDBS. The gain ranges from 0 dB to 50 dB forcontrol voltages between 0 V and 1.5 V?a slope of 30 mV/dB.The gain linearity is typically within ?0.1 dB. By changing thelogic level on Pin MODE, the gain decreases over the same range,with an opposite slope. A second gain control port is providedat the VMAG pin and allows the user to vary the numeric gainfrom a factor of 0.03 to 10. All the parameters of the AD8330have low sensitivities to temperature and supply voltages. UsingVMAG, the basic 0 dB to 50 dB range can be repositioned toany value from 20 dB higher (that is, 20 dB to 70 dB) to at least30 dB lower (that is, ?30 dB to +20 dB) to suit the application,thereby providing an unprecedented gain range of over 100 dB.A unique aspect of the AD8330 is that its bandwidth and pulseresponse are essentially constant for all gains, over both thebasic 50 dB linear-in-dB range, but also when using the linearin-magnitudefunction. The exceptional stability of the HFresponse over the gain range is of particular value in those VGAapplications where it is essential to maintain accurate gain lawconformanceat high frequencies.An external capacitor at Pin OFST sets the high-pass corner ofan offset reduction loop, whose frequency can be as low as 5 Hz.When this pin is grounded, the signal path becomes dc-coupled.When used to drive an ADC, an external common-mode controlvoltage at Pin CNTR can be driven to within 0.5 V of either groundor VS to accommodate a wide variety of requirements.

Low power architecture improves power efficiency.APPLICATIONS Wireless communications: 3G/4G and MC-GSM base stations, wideband repeaters, software defined radios Wideband communications: point-to-point, LMDS/MMDS Transmit diversity/MIMO Instrumentation Automated test equipment
