EL4450
FN7168
Wideband Four-Quadrant Multiplier
The EL4450 is a complete fourquadrant multiplier circuit. It offers wide bandwidth and good linearity while including a powerful output voltage amplifier, drawing modest supply current. The EL4450 operates on ±5V supplies and has an analog input range of ±2V, making it ideal for video signal processing. AC characteristics do not vary over the ±5V to ±15V supply range. The multiplier has an operational temperature range of -40°C to +85°C and are packaged in plastic 14-pin PDIP and SO.
Features
· Complete four-quadrant multiplier with output amp-- requires no extra components · Good linearity of 0.3% · 90MHz bandwidth for both X and Y inputs · Operates on ±5V to ±15V supplies · All inputs are differential · 400V/µs slew rate
Applications
· Modulation/Demodulation · RMS computation

CAUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless otherwise noted, all tests are at the specified temperature and are pulsed tests, therefore: TJ = TC = TA
