Product Overview

The LM94023BITME/NOPB is a precision CMOS Temperature Sensor with a class-AB output structure gives the device strong output source and sink current capability for driving heavy loads, making it well suited to source the input of a sample-and-hold analogue-to-digital converter with its transient load requirements, This generally means the device can be used without external components, like resistors and buffers, on the output. The device delivers an output voltage that is inversely proportional to measured temperature. The LM94023's low supply current makes it ideal for battery-powered systems as well as general temperature sensing applications. A Gain Select (GS) pin sets the gain of the temperature-to-voltage output transfer function. Either of two slopes are selectable, -5.5mV/°C (GS=0) or -8.2mV/°C (GS=1). Tying GS high causes the transfer f unction to have the largest gain for maximum temperature sensitivity.
  • Push-Pull output with ±50µA source current
  • Two selectable gains
  • Very accurate over wide temperature range of -50 to +150°C
  • Low quiescent current
  • Output is short-circuit protected
  • Green product and no Sb/Br
