LM94023 具有 AB 类输出的 1.5V、微型 SMD、双路增益模拟温度传感器
The LM94023 is a precision analog output CMOS integrated-circuit temperature sensor that operates at a supply voltage as low as 1.5 Volts. Available in the very small four-bump microSMD 0.8mm x 0.8mm) the LM94023 occupies very little board area. A class-AB output structure gives the LM94023 strong output source and sink current capability for driving heavy loads, making it well suited to source the input of a sample-and-hold analog-to-digital converter with its transient load requirements, This generally means the LM94023 can be used without external components, like resistors and buffers, on the output. While operating over the wide temperature range of −50°C to +150°C, the LM94023 delivers an output voltage that is inversely porportional to measured temperature.
