The MAX6034 precision, low-dropout, micropower voltage references are available in a miniature 3-pin SC70 surface-mount package. They feature a proprietary, temperature-coefficient, curvature-correction circuit and laser-trimmed, thin-film resistors that result in a low temperature coefficient of 30ppm/°C (max) and initial accuracy of ±0.20% (max). These devices are available over the extended temperature range of -40°C to +85°C.
The MAX6034 series-mode voltage references typically draw only 90µA of supply current and can source 1mA and sink 200µA of load current. Unlike conventional shunt-mode (two terminal) references that waste supply current and require an external resistor, devices in the MAX6034 family offer supply current that is virtually independent of supply voltage (16µA/V, max variation) and do not require an external resistor. These internally compensated devices do not require an external compensation capacitor, but are stable with up to 1µF of load capacitance. Eliminating the external compensation capacitor saves valuable board space in space-critical applications. The low dropout voltage and supply-independent, ultra-low supply current make the MAX6034 ideal for battery-powered applications.
