Pin-Programmable, Precision Voltage
Reference
General Description
Maxim’s MX584 is a temperature-compensated,
bandgap voltage reference which provides pin-program-
mable output voltages of +10.00V, +7.50V, +5.00V, and
+2.50V. External components are not required for these
outputs, but if other voltages are desired, they can be
programmed with external resistors.
Laser trimming minimizes output error as well as tem-
perature drift, to as low as 10mV and 15ppm/°C with
the MX584K.
The input voltage range of the MAX584 is 4.5V to 30V.
The reference also includes a STROBE input which
shuts down the reference output. Typical current drain
when ON is 750µA. This drops to about 100µA when
the reference is strobed OFF.
The MX584 is designed for use with 8- to 14-bit A/D
and D/A converters as well as data acquisition systems.
It is available in 8-lead TO-99 metal cans, plastic DIPS,
CERDIPS, and SO packages.

Detailed Description
As shown in Figure 1, most applications of the MX584
require no external components. Connections to +V
S
and COMMON (COMMON is also tied to the case in the
TO-99 metal package) with all other pins unconnected
result in a buffered +10.00V output at pin 1. The other
pretrimmed voltages are obtained by strapping pins as
shown in Table 1. If one or more external buffer ampli-
fiers are connected to the programming pins (pins 2, 3),
multiple outputs can be obtained from one reference.

Connect pins 3 and 1 together
Other Output Voltages
The MX584 can be adjusted to a different output volt-
age by adding one or more resistors as in Figure 2. As
the diagram shows, the reference can be thought of as
a 1.215V bandgap followed by a noninverting amplifier.
If R1 and R2 are used alone, the adjustment range is
widest but the resolution of the trim may be too coarse,
even when a multi-turn trip pot is used.
When adding external resistors, output voltages well
above 10V can be obtained. R2 should therefore be
chosen carefully since it sets the maximum output volt-
age. R2’s resistance should not be so low as to jeopar-
dize other circuits if R1 is misadjusted.
The fixed output voltages can also be varied by con-
necting only one resistor, as in the dashed lines in
Figure 2. Connecting R3 alone raises V
OUT
while R4
alone lowers it. These resistors (or potentiometers)
must have very low temperature coefficients if accuracy
over temperature is to be unaffected by the adjustment.
If fine adjustment of the output is all that is required, the
circuit of Figure 3 is recommended. It provides good
stability and resolution for a trim range of ±200mV. If
the 2.5V output is adjusted, R2 should be connected to
V
BG
, pin 6, and the trim range should be limited to
±100mV.

Voltage Temperature Coefficient
The temperature characteristic of the MX584 consis-
tently follows an "S-curve" as shown in the
Typical
Operating Characteristics.
A five-point 100% test guar-
antees compliance with -55°C to +125°C specifications
and a three-point 100% test guarantees 0°C to +70°C
specifications.
The tolerance specifications in the
Electrical
Characteristics
table state the maximum deviation from
the reference’s initial value at +25°C. By adding the
maximum deviation for a given device to its initial toler-
ance, the total possible error is determined.
