Product Summary

The AD8330ARQZ-REEL7 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 150 MHz. The input pins can also be driven from a single-ended source. The peak differential input is ±2 V, allowing sine wave operation at 1 V rms with generous headroom. The output pins can drive single-sided loads essentially rail-to-rail. The differential output resistance is 150 Ω. The output swing of AD8330ARQZ-REEL7 is a linear function of the voltage 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 typical aplications of AD8330ARQZ-REEL7 include: (1)Pre-ADC signal conditioning; (2)75 Ω cable driving adjust; (3)AGC amplifiers.
