High-Precision Voltage References with
Temperature Sensor
The MAX6173–MAX6177 precision voltage references
provide accurate preset +2.5V, +3.3V, +4.096V, +5.0V,
and +10V reference voltages from up to +40V input volt-
ages. These devices feature a proprietary temperature-
coefficient curvature-correction circuit and laser-trimmed
thin-film resistors that result in a very low 3ppm/°C tem-
perature coefficient and excellent 0.05% initial accuracy.
The MAX6173–MAX6177 draw 340µA of supply current
and source 30mA or sink 2mA of load current.
Trim the factory-preset output voltage on the
MAX6173–MAX6177 by placing a resistive divider net-
work between OUT, TRIM, and GND.

Use the following formula to calculate the change in

For example, use a 50kΩ 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
output voltage changes accordingly. Set R2 to 1MΩ or
less. Currents through resistors R1 and R2 add to the
quiescent supply current.
