The MLT04 is a complete, four-channel, voltage output analog multiplier packaged in an 18-pin DIP or SOIC-18. These complete multipliers are ideal for general purpose applications such as voltage controlled amplifiers, variable active filters, "zipper" noise free audio level adjustment, and automatic gain control.

Other applications of MLT04 include cost-effective multiple-channel power calculations (I ´ V), polynomial correction generation, and low frequency modulation. The MLT04 multiplier is ideally suited for generating complex, high-order waveforms especially suitable for geometry correction in high-resolution CRT display systems Fabricated in a complementary bipolar process, the MLT04 Includes four 4-quadrant multiplying cells which have been lasertrimmed for accuracy. A precision internal bandgap reference normalizes signal computation to a 0.4 scale factor. Drift over temperature is under 0.005%/°C. Spot noise voltage of 0.3 mV/ÖHz results in a THD + Noise performance of 0.02% (LPF = 22 kHz) for the lower distortion Y channel. The four 8 MHz channels consume a total of 150 mW of quiescent power.

The MLT04 is available in 18-pin plastic DIP, and SOIC-18 surface mount packages. All parts are offered in the extended industrial temperature range (40°C to +85°C).
