Product Details
The MAX6072 is a dual-output precision series voltage reference. The product features two outputs, +VREF and +VREF/2. The device exhibits a very low 1/f noise of 2ppm (peak-to-peak). Each output can source and sink 10mA and has an independent sense line. This product has a temperature drift of 6ppm/°C (max) over the ambient temperature range of -40°C to +125°C and an initial accuracy of 0.04%. Three pairs of output voltages are available: 5V/2.5V, 4.096V/2.048V, and 2.5V/1.25V. The product operates with an input voltage range of 2.8V to 5.5V and has sufficient headroom for the highest voltage. It consumes a mere 150µA (typ) of quiescent supply current per reference. The dual voltage outputs make this device ideal for precision ADC applications where the input signal needs to be referred to VREF/2.
The MAX6072 is available in a 10-pin μMAX® package and is specified for operation over the extended −40°C to +125°C industrial temperature range.
