FAMILY
The MC1404 series of ICS is a family of temperature-compensated
voltage references for precision data conversion applications, such as
A/D, D/A, V/F, and F/V. Advances in lase~trimming and ion-
implanted devices, as well as monolithic fabrication techniques,
make these devices stable and accurate to 12 bits over both military
and commercial temperature ranges. In addition to excellent tem-
perature stability, these parts offer excellent long-term stability and
low noise.
