Overview
The LT1011AMJ8 is a general-purpose voltage comparator manufactured by Analog Devices Inc. It features an 8-lead CERDIP package and operates within a temperature range of -55°C to 125°C. Key electrical specifications include a maximum input offset voltage of 0.5mV, a maximum input bias current of 25nA, and a guaranteed minimum voltage gain of 200,000 V/mV. The device supports single or dual supply operation from 3V to ±18V, with a response time of 250ns maximum and a floating output capable of sourcing or sinking 50mA.
Feature Summary
- Pin compatible with LM111 series devices while offering improved input characteristics
- Floating transistor output allows driving loads referenced to ground, negative, or positive supplies
- Strobe pin enables forcing the output transistor into an off state
- Balanced inputs allow for offset adjustment and hysteresis addition
Applications
- SAR A/D Converters
- Voltage-to-Frequency Converters
- Precision RC Oscillators
- Peak Detectors
- Motor Speed Control
Procurement Notes
Verify the specific ordering suffix and lead finish configuration against the manufacturer's official documentation before procurement. Confirm that the obsolete status of the TO-5 metal can package does not impact long-term availability requirements. Ensure the selected variant matches the required operating temperature range and package type for the intended application environment.
Selection Notes
Select this component when high precision and fast switching are required in a general-purpose comparator application. Consider the LT1011AMJ8 for designs needing low input bias current and low offset voltage drift. Evaluate the need for strobing functionality and the ability to drive high-current loads directly without external buffering. Verify compatibility with existing circuit topologies designed for the LM111 series.
Part Context
The LT1011 series represents a family of precision voltage comparators designed to replace older LM111 devices with enhanced performance metrics. The AMJ8 designation specifically refers to the military-grade temperature range version housed in a ceramic dual in-line package. This part belongs to the broader LT1011 product line which includes plastic DIP and SOIC variants for different thermal and mechanical requirements.
