LT1017IN8#PBF

LT1017 is a general purpose micropower comparator. It operates from a single 1.1V cell upto 40V. 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 comparators 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. It is used in applications such as power supply monitors, relay driving, oscillators.

• Offset voltage is 1mV maximum at (±0.75V ≤ VS ≤ ±20V)
• Bias current is 5nA typical (±0.75V ≤ VS ≤ ±20V)
• Common mode rejection ratio is 115dB typical at (VS = ±20V, –20V ≤ VCM ≤ 19.1V)
• Internal pull-up current, output can drive loads above V+
• Supply current is 30μA typical at (VS = 5V)
• Output sink current is 65mA typical at (V+ = 4.5V, V– = 0V)
• Power supply rejection ratio is 110dB typical at ( ±0.75V ≤ VS ≤ ±20V)
• Offset current is 0.4nA typical at (±0.75V ≤ VS ≤ ±20V)
• Operating temperature is -40°C to 85°C, package style is 8-lead PDIP
