LM94022BIMG/NOPB

Датчик температуры (ИС), Напряжение, ± 2.7°C, -50 °C, +150 °C, SC-70, 5 вывод(-ов).

The LM94022BIMG/NOPB is a precision CMOS Temperature Sensor with selectable linear negative temperature coefficient (NTC). A class-AB output structure gives the LM94022/-Q1 strong output source and sink-current capability for driving heavy transient loads such as that presented by the input of a sample-and-hold analogue-to-digital converter. The Gain Select 1 (GS1) and Gain Select 0 (GS0) logic inputs select one of four gains for the temperature-to-voltage output transfer function, -5.5mV/°C, -8.2mV/°C, -10.9mV/°C and -13.6mV/°C. Maximum temperature sensitivity, -13.6mV/°C, is selected when GS1 and GS0 are both tied high. The gain-select inputs can be tied directly to VDD or Ground without any pull-up or pull-down resistors, reducing component count and board area. These inputs can also be driven by logic signals allowing the system to optimize the gain during operation or system diagnostics.
