Overview
The AD834JNZ, produced by Analog Devices Inc., is a monolithic, laser-trimmed four-quadrant analog multiplier. It is designed for high-frequency applications, offering a transconductance bandwidth in excess of 500 MHz from either of the differential voltage inputs. This device is particularly useful in applications requiring high static accuracy and very high bandwidth, making it suitable for a variety of high-speed nonlinear operations.
The AD834JNZ is available in an 8-lead PDIP package and is specified over the commercial temperature range of 0°C to 70°C. Its 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.
