The 4213 multiplier-divider is a low cost precision device designed for general purpose application. In addition to four-quadrant multiplication, it also performs analog square root and division without the bother of external amplifiers. The 4213 is laser-trimmed to guarantee its rated accuracy with no external components. The internal zener regulated references make the 4213 much less sensitive to supply variation than earlier IC multipliers. hermetic TO-100 package, wide operating temperature range, low output noise, and low cost are some of the desirable features of this versatile device.
