LT1018CS8#PBF

LT1018 is a general purpose micropower dual comparator. Operates at higher power and higher speed. The output stage includes a class B pullup current source, eliminating the need for an external resistive pull-up and saving power. The output stage is also designed to allow driving loads connected to a supply more positive than the device, as can comparator with open-collector output stages. Input specifications are also excellent. On-chip trimming minimizes offset voltage, while high gain and common mode rejection ratio keep other input referred errors low. Common mode voltage range includes ground. Special circuitry prevents false output states even if the input is overdriven. Typical applications are power supply monitors, relay driving, oscillators.

• Offset voltage is 1mV at ±0.75V ≤ VS ≤ ±20V, 25°C
• Bias current is 75nA at ±0.75V ≤ VS ≤ ±20V, 25°C
• Output sink current is 70mA at V+ = 4.5V, V– = 0V, overdrive <gt/> 30mV, 25°C
• Internal pull-up current
• Output can drive loads above V+
• Supply current is 250μA at VS = 5V, 25°C
• Minimum operating voltage is 1.2V at IOUT = 1mA, 25°C
• 8-lead plastic SO package
• Operating temperature range from 0°C to 70°C
