Product Summary

The LM293DR2G is a dual independent precision voltage comparator capable of single or split supply operation.

Parametrics

LM293DR2G absolute maximum ratings: (1)Power supply voltage, VCC: +36 or ±18Vdc; (2)Input differential voltage range, VIDR: 36Vdc; (3)Input common mode voltage range, VICR: -0.3 to +36Vdc; (4)Output sink current, Isink: 20mA; (5)Power dissipation @TA=25℃, PD: 570mW; (6)Operating ambient temperature range, TA: -25 to +85℃; (7)Maximum operating junction temperature, TJ: 150℃; (8)Storage temperature range, Tstg: -65 to +150℃.

Features

LM293DR2G features: (1)Wide single-supply range: 2.0Vdc to 36Vdc; (2)Split-supply range: ±1.0Vdc to ±18Vdc; (3)Very low current drain independant of supply voltage: 0.4mA; (4)Low input bias current: 25nA; (5)Low input offset current: 5.0nA; (6)Low input offset voltage: 5.0mV; (7)Input common mode range to ground level; (8)Differential input voltage range equial to power supply voltage; (9)Output voltage compatible with DTL, ECL, TTL, MOS, and CMOS logic level; (10)ESD clamps on the inputs increase the ruggedness of the device without affecting performance.
