AD834JRZ

AD834 is a monolithic, laser-trimmed four-quadrant analogue multiplier intended for use in high frequency applications, with a trans conductance bandwidth (RL=50 ohm) in excess of 500MHz from either of the differential voltage inputs. In multiplier modes, the typical total full-scale error is 0.5%, dependent on the application mode and the external circuitry. Performance is relatively insensitive to temperature and supply variations due to the use of stable biasing based on a band gap reference generator and other design features. To preserve the full bandwidth potential of the high speed bipolar process used to fabricate the AD834, the outputs appear as a differential pair of currents at open collectors. Typical application includes high speed real time computation, wideband modulation and gain control, signal correlation and RF power measurement, voltage controlled filters and oscillators, linear keyers for high resolution television and wideband true RMS.
