The MC1404 of ICs is a family of temperaturecompensated voltage references for precision data conversion applications, such as A/D, D/A, V/F, and F/V. Advances in lasertrimming and ionimplanted 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 temperature stability, these parts offer excellent longterm stability and low noise.
