FUNCTION
Internally Connected. Do not connect externally.
Positive Power-Supply Input
Temperature Proportional Output Voltage. TEMP generates an output voltage proportional to the die
temperature.
Ground
Output Voltage Trim. Connect TRIM to the center of a voltage-divider between OUT and GND for
trimming. Leave unconnected to use the preset output voltage.
Output Voltage
No Connection. Not internally connected.
Detailed Description
The MAX873/MAX875/MAX876 precision voltage refer-
ences provide accurate preset +2.5V, +5.0V, and +10V
reference voltages from up to +40V input voltages. These
devices feature a proprietary temperature-coefficient
curvature-correction circuit and laser-trimmed thin-film
resistors that result in a very low 3ppm/ ° C temperature
coefficient and excellent 0.05% initial accuracy. The
MAX873/MAX875/MAX876 draw 340μA of supply current
and source 30mA or sink 2mA of load current.
Trimming the Output Voltage
Trim the factory-preset output voltage on the
MAX873/MAX875/MAX876 by placing a resistive divider
network between OUT, TRIM, and GND.
Use the following formula to calculate the change in
output voltage from its preset value:
? V OUT = 2 x (V TRIM - V TRIM (open) ) x k
where:
V TRIM = 0V to V OUT
V TRIM (open) = V OUT (nominal) / 2 (typ)
k = ± 6% (typ)
For example, use a 50k ? potentiometer (such as the
MAX5436) between OUT, TRIM, and GND with the
potentiometer wiper connected to TRIM (see Figure 2).
As the TRIM voltage changes from V OUT to GND, the
output voltage changes accordingly. Set R2 to 1M ? or
less. Currents through resistors R1 and R2 add to the
quiescent supply current.
