What are the key features of LT1017IS8#TRPBF?
- Ultra-low 25 nA maximum input bias current enabling direct connection to high-impedance sensor outputs without loading errors
- Single or dual supply operation up to ±20 V accommodating a wide range of analog system supply architectures
- 1.4 mV maximum input offset voltage for accurate threshold detection in precision level sensing applications
- Open-collector outputs compatible with TTL, CMOS, and ECL logic levels for versatile digital interface options
- Micropower supply current below 100 µA total, ideal for battery-operated and always-on sensing circuits
What is LT1017IS8#TRPBF used for?
The LT1017IS8 is used in battery-powered instruments and remote sensor nodes where its ultra-low 25 nA bias current and micropower supply consumption below 100 µA allow continuous threshold monitoring without measurably draining the battery. Precision window comparator circuits in industrial 4–20 mA transmitters, over-temperature alarms, and under-voltage lockout circuits benefit from the 1.4 mV offset accuracy and wide ±20 V supply range. The open-collector outputs also make it a natural fit for wire-OR bus arbitration and mixed-voltage flag signaling between 3.3 V microcontroller GPIOs and legacy 5 V or 12 V control logic.

Frequently Asked Questions
How low is the input bias current of the LT1017IS8 and why does it benefit high-impedance sensor interfaces?
The LT1017IS8 specifies a maximum input bias current of only 25 nA, which causes less than 25 µV of error even when connected to a 1 MΩ source impedance. This makes it suitable for interfacing directly with piezoelectric sensors, pH electrodes, and photodiode circuits that cannot tolerate comparator input loading without adding a unity-gain buffer stage.
What supply voltage range does the LT1017IS8 support and can it work in ±15 V instrumentation systems?
The LT1017IS8 operates from a single supply of 2 V to 36 V or dual supplies up to ±18 V, comfortably fitting within ±15 V precision instrumentation power rails common in industrial analog systems. The wide supply range means one comparator part covers both low-voltage microcontroller boards and higher-voltage analog front-end circuits without design changes.
How does the LT1017IS8 compare to a standard LM393 in a battery-powered IoT threshold detector?
The LT1017IS8 consumes under 100 µA total supply current versus the LM393's typical 400 µA, reducing idle power by 4x in an always-on comparator circuit. Over one year of continuous operation from a 1,000 mAh battery, this difference saves approximately 2,600 mAh, effectively quadrupling battery life compared to using the LM393 in the same design.
Are the LT1017IS8 outputs compatible with 3.3 V microcontroller GPIO inputs?
Yes, the LT1017IS8 has open-collector outputs that can be pulled up to any voltage within the supply range, including 3.3 V, 5 V, or 12 V. Connecting a 100 kΩ pull-up resistor to 3.3 V makes the output directly readable by a microcontroller GPIO, while the same device output can simultaneously interface with a 5 V TTL logic input on another board via a separate pull-up resistor.
