MAX873AESA+

The MAX873AESA+ is a low drift, 2.5V precision voltage reference in 8 pin NSOIC package. This voltage reference offers excellent accuracy and very low power consumption. Extremely low temperature drift combined with excellent line and load regulation permit stable operation over a wide range of electrical and environmental conditions. The device is suitable for 12bit data acquisition. A TRIM pin facilitates adjustment of the reference voltage over a ±6% range using only a 100Kohm potentiometer. A voltage output proportional to temperature provides a source for temperature compensation circuits, temperature warning circuits and other applications.

• Supply voltage range from 4.5V to 18V
• Operating temperature range from -40°C to 85°C
• Initial accuracy is ±0.06%
