Precision High-Voltage Reference in SOT23
General Description
Features
ꢀ +2.5V, +3.3V, +4.096V, +5.0V, or +10V Output
The MAX6043 precision voltage reference provides
accurate preset +2.5V, +3.3V, +4.096V, +5.0V, and
+10V reference voltages from up to +40V input volt-
ages. The MAX6043 features a proprietary temperature
coefficient curvature-correction circuit and laser-
trimmed thin-film resistors that result in a very low tem-
perature coefficient of 15ppm/°C (max) and excellent
initial accuracy of 0.05% (max). Low temperature drift
and low noise make the MAX6043 ideal for use with
high-resolution A/D or D/A converters.
Voltages
ꢀ Excellent Temperature Stability: 15ppm/°C (max)
ꢀ Tight Initial Accuracy: 0.05% (max)
ꢀ Tiny SOT23 Package
ꢀ Wide +4.5V to +40V Supply Voltage Range
ꢀ Low Noise: 4µV
(typ at 2.5V Output)
P-P
ꢀ Short-Circuit Protected
ꢀ Wide Operating Temperature Range
The MAX6043 draws 320µA of supply current and
sources 10mA or sinks 0.6mA of load current. The
MAX6043 uses bandgap technology for low-noise per-
formance and excellent accuracy. The MAX6043 does
not require an output bypass capacitor for stability, and
is stable with capacitive loads up to 100µF. Eliminating
the output bypass capacitor saves valuable board area
in space-critical applications. The supply-independent,
low supply current makes the MAX6043 ideal for bat-
tery-operated, high-performance systems.
-40°C to +125°C
ꢀ Stable with Capacitive Loads from 0 to 100µF
ꢀ No External Capacitors Required for Stability

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Turn-On Time
The MAX6043 typically turns on and settles to within
0.05% of the preset output voltage in 150µs.
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.
Short-Circuited Outputs
The MAX6043 features a short-circuit-protected output.
Internal circuitry limits the output current to 60mA when
short-circuiting the output.
The MAX6043 does not require an output capacitor for
stability and is stable with capacitive loads up to 100µF.
In applications where the load or the supply can experi-
ence step changes, a larger output capacitor reduces
the amount of overshoot (undershoot) and improves the
circuit’s transient response. Place output capacitors as
close to the device as possible 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 MAX6043 consumes 320µA of quiescent supply
current. This improved efficiency reduces power dissi-
pation and extends battery life.

parameter. The graph assumes the reference-voltage
temperature coefficient as the only parameter affecting
accuracy.
Thermal Hysteresis
Thermal hysteresis is the change in the output voltage
at T = +25°C before and after the device is cycled
A
In reality, the absolute static accuracy of a data convert-
er is dependent on the combination of many parameters
such as integral nonlinearity, differential nonlinearity,
offset error, gain error, as well as voltage-reference
changes.
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 150ppm.
