MC1404
Voltage Reference Family
The MC1404 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 laser–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 temperature stability, these parts offer excellent long–term
stability and low noise.
• Output Voltages: Standard, 5.0 V, 6.25 V, 10 V
• Trimmable Output: > ± 6%
• Wide Input Voltage Range: Vref + 2.5 V to 40 V
• Low Quiescent Current: 1.25 mA Typical
• Temperature Coefficient: 10 ppm/°C Typical
• Low Output Noise: 12 µV p–p Typical
• Excellent Ripple Rejection: > 80 dB Typical
Typical Applications
• Voltage Reference for 8 to 12 Bit D/A Converters
• Low TC Zener Replacement
• High Stability Current Reference
• MPU D/A and A/D Applications
