DESCRIPTION
VRE120 series references are designed to operate over an extremely wide temperature range (-55°C to +180°C) and still provide excellent accuracy. The VRE120 provides a +10V output, the VRE121 provides a -10V and the VRE122 provides a ±10V output. All types are available in commercial (C suffix) and military (M suffix) models. The "M" models are screened for high reliability and quality. Two accuracy grades (standard and "A") are available for all models. SELECTION GUIDE

The adjacent selector guide shows the limits of the VRE121C -10V 1.5mV 5.0mV 1.0mV most important parameters of the VRE120 series VRE121CA -10V 1.0mV 3.0mV 0.5mV voltage references. The maximum voltage VRE121M -10V 1.5mV 5.0mV 1.5mV deviation increases linearly with temperature from VRE121MA -10V 1.0mV 3.0mV 0.8mV the 150°C specification to the 180°C specification. For example, the A grade maximum voltage VRE122C ±10V 1.5mV 5.0mV 1.0mV deviation of 1mV increases to 2mV at 175°C and is VRE122CA ±10V 1.0mV 3.0mV 0.5mV 3mV at 180°C. This degree of accuracy over such VRE122M ±10V 1.5mV 5.0mV 1.5mV a large temperature range has been achieved VRE122MA ±10V 1.0mV 3.0mV 0.8mV using the Thaler Corporation patented multipoint compensation technique. All devices are packaged in 14-pin hermetic ceramic packages for maximum long term stability. They are pin and function compatible with other Thaler references and AD2700, AD2710 and MAX 670/671 References Superior stability, accuracy, and quality make these references ideal for precision applications such as A/D and D/A converters, high-accuracy test and measurement instrumentation, and transducer excitation.
