Order this document by MC1404/D 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 • • • • • • PRECISION LOW DRIFT VOLTAGE REFERENCES 5.0, 6.25, and 10–VOLT OUTPUT VOLTAGES SEMICONDUCTOR TECHNICAL DATA 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 8 Low TC Zener Replacement 1 High Stability Current Reference MPU D/A and A/D Applications P SUFFIX PLASTIC PACKAGE CASE 626 Figure 1.

For example, the output can be set to 10.000 V or to 10.240 V for binary applications. For trimming, Bourns type 3059, 100 kΩ or 200 kΩ trimpot is recommended. Although Figure 10 illustrates a wide trim range, temperature coefficients may become unpredictable for trim > ± 6.0%. 5.0, 6.25, 10 V @ 1/2 Amp Output Power Boosting Gnd 4 The addition of a power transistor, a resistor, and a capacitor converts the MC1404 into a precision supply with one ampere current capability. At V+ = 15 V, the MC1404 can carry in excess of 14 mA of load current with good regulation. If the power transistor current gain exceeds 75, a one ampere supply can be realized. Figure 12.
