MC1504 Voltage Reference

.—. =, MC1404 MC1404A MC1504 MC1504A VOLTAGE REFERENCE 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 ionimplanted devices, as well as monolithic fabrication techniques, make these devices stable and accura.
