DESCRIPTION
The MPY100 multiplier-divider is a low cost preci-
sion 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 or potentiometers. Laser-
trimmed one-chip design offers the most in highly
reliable operation with guaranteed accuracies.
Because of the internal reference and pretrimmed
accuracies the MPY100 does not have the restrictions
of other low cost multipliers. It is available in both
TO-100 and DIP ceramic packages.
