The MAX6035 is a high-voltage, precision micropower
voltage reference. This three-terminal device is available
with output voltage options of 2.5V, 3.0V, and 5.0V. It is an
excellent upgrade for industry-standard devices such as
the REF02 and REF43. The MAX6035 offers 14x lower
power than the REF02 and 5x lower power than the
REF43, as well as a reduced package size from an 8-pin
SO to a 3-pin SOT23. The MAX6035 features a proprietary
temperature coefficient curvature-correction circuit and
laser-trimmed, thin-film resistors that result in a very low
temperature coefficient of 25ppm/°C (max) and an initial
accuracy of ±0.2% (max).
The MAX6035 typically draws only 73µA of supply cur-
rent and can source 10mA or sink 2mA of load current.
Unlike conventional shunt-mode (two-terminal) refer-
ences that waste supply current and require an external
resistor, this device offers a supply current that is virtu-
ally independent of the supply voltage and does not
require an external resistor. Additionally, this internally
compensated device does not require an external com-
pensation capacitor, but is also stable with capacitive
loads up to 5µF. Eliminating the external compensation
capacitor saves valuable board area in space-critical
applications. The supply independent, ultra-low supply
current makes this device ideal for battery-operated,
high-performance systems.
The MAX6035 is available in a 3-pin SOT23 package
and is specified for operation from -40°C to +125°C.
