GE NE RAL DE SCRIPT ION
T he MLT 04 is a complete, four-channel, voltage output analog
multiplier packaged in an 18-pin DIP or SOIC-18. T hese 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
×
V), polynomial correction generation, and low frequency
modulation. T he MLT 04 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 MLT 04
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%/

Hz
results in a T HD + Noise performance of 0.02% (LPF = 22 kHz)
for the lower distortion Y channel. T he four 8 MHz channels
consume a total of 150 mW of quiescent power.
T he MLT 04 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).
