描述

LM56是一款精密低功耗恒溫器。通過(guò)使用3個(gè)外部電阻分壓LM56 1.250V帶隙電壓基準(zhǔn)，可以產(chǎn)生兩個(gè)穩(wěn)定的溫度跳變點(diǎn)（V _T1和V _T2）。 LM56有兩個(gè)數(shù)字輸出。當(dāng)溫度超過(guò)T1時(shí)，OUT1變?yōu)榈碗娖剑?dāng)溫度低于T1時(shí)，OUT1變?yōu)楦唠娖剑═1-T _HYST）。類似地，當(dāng)溫度超過(guò)T2時(shí)OUT2變?yōu)榈碗娖剑?dāng)溫度低于T2時(shí)變?yōu)楦唠娖剑═2-T _HYST）。 T _HYST是內(nèi)部設(shè)置的5°C典型遲滯。

LM56采用8引腳VSSOP表面貼裝封裝和8引腳SOIC封裝。
