Product Summary

The LM339N is a low power quad voltage comparator. The LM339N consists of four independent preci-sion voltage comparators with an offset voltage specifications as low as 2mV max. The comparator was designed specifically to operate from a sin-gle power supply aver a wide range of voltages. Operation from split power supplies is also possi-ble. The LM339N also has a unique character-istic in that the input common-mode voltage range includes ground even though operated from a sin-gle power supply voltage.

Parametrics

LM339N absolute maximum ratings: (1)Supply voltage, VCC: ±18 or 36 V; (2)Differential Input Voltage, Vid: ±36 V; (3)Input Voltage, Vi: -0.3 to +36 V; (4)Output Short-circuit to Ground: Infinite; (5)Power Dissipation, DIP14, Pd: 1500mW; (6)Storage Temperature Range, Tstg: -65 to +150℃; (7)Junction Temperature, Tj: +150℃.

Features

LM339N features: (1)Wide single supply voltage range or dual supplies for all devices: +2V TO +36V OR ±1V TO ±18V; (2)Very low supply current (1.1ma) independent of supply voltage; (3)(1.4mW/comparator at +5V); (4)Low input bias current: 25nA typ; (5)Low input offset current: ±5nA typ; (6)Low input offset voltage: ±1mV typ; (7)Input common-mode voltage range includes ground; (8)Low output saturation voltage: 250mV Typ; (Io = 4mA); (9)Differential input voltage range equal to the supply voltage; (10)TTL, DTL, ECL, MOS, CMOS compatible outputs.
