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 Adjustment
The MC1404 trim terminal can be used to adjust the output voltage
over a ± 6.0% range. 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%.

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.
