STMicroelectronics LM139, LM239 & LM339 Quad Voltage Comparators
STMicroelectronics LM139, LM239, and LM339 Low-Power Quad Voltage Comparators consist of four independent precision-voltage comparators with an offset voltage specification as low as 2 mV. These Low-Power Quad Voltage Comparators have been designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible. STMicroelectronics' Low-Power Quad Voltage Comparators also have a unique characteristic in that the input common mode voltage range includes ground even though operated from a single power supply voltage.
Features
- Wide single supply voltage range or dual supplies for all devices: +2V to +36V or ±1V to ±18V
- Very low supply current (1.1mA) independent of supply voltage
- Low input bias current: 25nA typ
- Low input offset current: ±5nA typ
- Low input offset voltage: ±1mV typ
- Input common-mode voltage range includes ground
- Low output saturation voltage: 250mV typ; (ISINK = 4mA)
- Differential input voltage range equal to the supply voltage
- TTL, DTL, ECL, MOS, CMOS compatible outputs
