MAX6173–MAX6177
High-Precision Voltage References with
Temperature Sensor
General Description
Features
+ 2V) to +40V Supply Voltage Range
The MAX6173–MAX6177 are low-noise, high-precision
voltage references. The 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 0.06%
initial accuracy. The MAX6173–MAX6177 provide a
TEMP output where the output voltage is proportional to
the die temperature, making the devices suitable for a
wide variety of temperature-sensing applications. The
devices also provide a TRIM input, allowing fine trimming
of the output voltage with a resistive divider network. Low
temperature drift and low noise make the devices ideal
for use with high-resolution A/D or D/A converters.
o Wide (V

o Excellent Temperature Stability: 3ppm/°C (max)
o Tight Initial Accuracy: 0.05% (max)
o Low Noise: 3.8µV
(typ at 2.5V Output)
P-P
o Sources up to 30mA Output Current
o Low Supply Current: 450µA (max at +25°C)
o Linear Temperature Transducer Voltage Output
o +2.5V, +3.3V, +4.096V, +5.0V, or +10V Output
Voltages
o Wide Operating Temperature Range: -40°C to
+125°C
The MAX6173–MAX6177 provide accurate preset +2.5V,
+3.3V, +4.096V, +5.0V, and +10V reference voltages and
accept input voltages up to +40V. The devices draw
320μA (typ) of supply current and source 30mA or sink
2mA of load current. The MAX6173–MAX6177 use
bandgap technology for low-noise performance and
excellent accuracy. The MAX6173–MAX6177 do not
require an output bypass capacitor for stability, and are
stable with capacitive loads up to 100μF. Eliminating the
output bypass capacitor saves valuable board area in
space-critical applications.
o No External Capacitors Required for Stability

temperature.

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.
For example, use a 50kΩ potentiometer (such as the
Detailed Description
MAX5436) between OUT, TRIM, and GND with the
potentiometer wiper connected to TRIM (see Figure 2).
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.
As the TRIM voltage changes from V
to GND, the
OUT
output voltage changes accordingly. Set R2 to 1MΩ or
less. Currents through resistors R1 and R2 add to the
quiescent supply current.
Temp Output
The MAX6173–MAX6177 provide a temperature output
proportional to die temperature. TEMP can be calculated
from the following formula:
Trimming the Output Voltage
Trim the factory-preset output voltage on the
MAX6173–MAX6177 by placing a resistive divider net-
work between OUT, TRIM, and GND.
TEMP (V) = T (°K) x n
J
where T = the die temperature,
J
n = the temperature multiplier,
Use the following formula to calculate the change in
output voltage from its preset value:
V
(at T = T )
J 0
TEMP
n =
≅ 1.9mV °K
ΔV
= 2 x (V
- V
) x k
TRIM (open)

Applications Information
Bypassing/Output Capacitance
For the best line-transient performance, decouple the
input with a 0.1μF ceramic capacitor as shown in the
Typical Operating Circuit. Place the capacitor as close
to IN as possible. When transient performance is less
important, no capacitor is necessary.
within 0.1% of the preset output voltage in 150μs (2.5V
output). The turn-on time can increase up to 150μs with
the device operating with a 1μF load.
Short-Circuited Outputs
The MAX6173–MAX6177 feature a short-circuit-protected
output. Internal circuitry limits the output current to
60mA when short circuiting the output to ground. The
output current is limited to 3mA when short circuiting
the output to the input.
The MAX6173–MAX6177 do not require an output
capacitor for stability and are stable with capacitive
loads up to 100μF. In applications where the load or the
supply can experience step changes, a larger output
capacitor reduces the amount of overshoot (under-
shoot) and improves the circuit’s transient response.
Place output capacitors as close to the devices as pos-
sible for best performance.
Temperature Coefficient vs. Operating
Temperature Range for a
1 LSB Maximum Error
In a data converter application, the reference voltage of
the converter must stay within a certain limit to keep the
error in the data converter smaller than the resolution
limit through the operating temperature range. Figure 1
shows the maximum allowable reference-voltage tem-
perature coefficient to keep the conversion error to less
than 1 LSB, as a function of the operating temperature
Supply Current
The MAX6173–MAX6177 consume 320μA (typ) of qui-
escent supply current. This improved efficiency
reduces power dissipation and extends battery life.
Thermal Hysteresis
Thermal hysteresis is the change in the output voltage
range (T
- T
) with the converter resolution as a

over its entire operating temperature range. Hysteresis
is caused by differential package stress appearing
across the bandgap core transistors. The typical ther-
mal hysteresis value is 120ppm.
In reality, the absolute static accuracy of a data con-
verter is dependent on the combination of many para-
meters such as integral nonlinearity, differential
nonlinearity, offset error, gain error, as well as voltage-
reference changes.
