AD8330ACPZ-R2 (ANALOG DEVICES)

The AD8330ACPZ-R2 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 peak differential input is ±2V, allowing sine wave operation at 1V RMS with generous headroom. The output pins can drive single-sided loads essentially rail-to-rail. The differential output resistance is 150R. The output swing is a linear function of the voltage applied to the VMAG pin that internally defaults to 0.5V, providing a peak output of ±2V. This can be raised to 10V p-p, limited by the supply voltage. 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. The gain linearity is typically within ±0.1dB.
