AD8330ARQZ

The AD8330ARQZ is a Wideband Variable Gain Amplifier for applications requiring a fully differential signal path, low noise, well-defined gain and moderately low distortion from DC to 150MHz. The input pins can also be driven from a single-ended source. The output pins can drive single-sided loads essentially rail-to-rail. The differential output resistance is 150R. The basic gain function is linear-in-dB, controlled by the voltage applied to Pin VDBS. The gain ranges from 0 to 50dB for control voltages between 0 and 1.5V, a slope of 30mV/dB. By changing the logic level on Pin MODE, the gain decreases over the same range, with an opposite slope. A second gain control port is provided at the VMAG pin and allows the user to vary the numeric gain from a factor of 0.03 to 10. Using VMAG, the basic 0 to 50dB range can be repositioned to any value from 20dB higher to at least 30dB lower to suit the application, thereby providing an unprecedented gain range of over 100dB.
