LM139AW-SMD

低功耗低失调电压四路比较器 14-CFP -55 to 125

This specially engineered electronic comparator circuit from Texas Instruments compares two input voltages and outputs a signal to tell you the larger of the two signals. Its maximum power dissipation is 680 mW. It has an open collector output. Its typical dual supply voltage is ±3|±5|±9|±12 V, with a minimum of ±2.5 V and maximum of ±15 V. This comparator has a minimum operating temperature of -55 °C and a maximum of 125 °C. This device uses one or two power supplies. It has 4 channels per chip. This device is made with bipolar technology. Its typical PSRR is 70Min dB.
