Product Summary
The LM239N is a Low-power quad voltage comparator. The device consists of four independent precision-voltage comparators with an offset voltage specification as low as 2 mV maximum for LM239N. Each comparator has been designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible.
Parametrics
LM239N absolute maximum ratings: (1)VCC, Supply voltage: ±18 or 36 V; (2)VID, Differential input voltage: ±36 V; (3)VIN, Input voltage: -0.3 to +36 V; (4)Output short-circuit to ground: Infinite; (5)Rthja, Thermal resistance junction to ambient: 80℃/W; (6)Rthjc, Thermal resistance junction to case: 33℃/W; (7)Tstg, Storage temperature range: -65 to +150℃; (8)Tj, Junction temperature: +150℃; (9)TLEAD, Lead temperature (soldering 10 seconds): 260℃; (10)ESD, Human body model (HBM): 500V.
Features
LM239N features: (1)Wide single supply voltage range or dual supplies for all devices: +2 to +36 V or ±1 V to ±18 V; (2)Very low supply current (1.1 mA) independent of supply voltage; (3)Low input bias current: 25 nA typ; (4)Low input offset current: ±5 nA typ; (5)Low input offset voltage: ±1 mV typ; (6)Input common-mode voltage range includes ground; (7)Low output saturation voltage: 250 mV typ;(ISINK = 4 mA); (8)Differential input voltage range equal to the supply voltage; (9)TTL, DTL, ECL, MOS, CMOS compatible outputs.
