Description
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.
Applications
- Modulation/Demodulation
- RMS computation
- Real-time power computation
- Nonlinearity correction/generation
