GENERAL DESCRIPTION
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 applica-
tions include cost-effective multiple-channel power calculations
(I
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 laser-
trimmed 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 V/ Hz
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).
