Precision High-Voltage Reference in SOT23
General Description
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.
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.
The MAX6043 is available in a 6-pin SOT23 package
and operates over the automotive (-40°C to +125°C)
temperature range.
