Converter has 100% overrange capability up to I IN = 2000 µA with slightly reduced linearity. Nonlinearity is defined as deviation from a straight line from zero to full scale, expressed as a percentage of full scale. 2 Guaranteed not tested. 3 Maximum voltage input level is equal to the supply on either input terminal. However, large negative voltage levels can be applied to the negative terminal if the input is scaled to a nominal 1 mA full scale through an appropriate value resistor (See Figure 2). 4 Loading the 1.0 volt or 1 mV/K outputs can cause a significant change in overall circuit performance, as indicated in the applications section. To maintain normal operation, these outputs should be operated into the external buffer or an external amplifier. 5 Temperature reference output performance is specified from 0 °C to +70°C for “J” and “K” devices, –55°C to +125°C for “S” model. 6 D = Ceramic DIP; H = Hermetic Metal Can. For outline information see Package Information section. 7 For AD537/883B specifications, refer to Analog Devices Military Products Databook. Specifications subject to change without notice. REV.
