ADI AD8330ARQ

可变增益差分，满摆幅

Overview

The AD8330ARQ 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 Ω. 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 AD8330ARQ is available in 16-lead LFCSP and 16-lead QSOPpackages and is specified for operation from −40°C to +85°C.
