本文推荐圣邦微(SGMICRO)推出的差分比较器SGM8770XS8G/TR,优势如下:
SGM8770XS8G/TR是一款双精度差分电压比较器,专为高压操作而优化。该装置可在2.8V至36V单电源或±1.4V至±18V双电源下工作。它在不受电源电压影响的情况下消耗低电源电流。输入共模电压比+V-S低1.5V。SGM8770具有需要外部上拉电阻器的开漏输出结构。
1、SGM8770XS8G/TR电压达到36V,电压范围更宽,可适用更多场景;
2、SGM8770XS8G/TR的电源电流典型值稍大于LM2903的,为310μA;
3、SGM8770XS8G/TR的偏移电压、偏置电流更小,性能更优;
4、SOIC-8封装,工作温度范围-40℃至+125℃,满足客户应用场景需求;
