Overview
The LT1011ACJG is a precision comparator manufactured by Texas Instruments, housed in an 8-pin Ceramic Dual In-Line Package (CDIP-8). It features a maximum input offset voltage of 1500 µV and a typical propagation delay of 150 ns. The device operates with a wide supply voltage range and includes separate output supply pins to accommodate various logic families. Key electrical characteristics include rise/fall times of 80 ns and 10 ns respectively, ensuring fast switching performance for analog-to-digital conversion and threshold detection applications.
Feature Summary
- Precision-trimmed input stage for low offset voltage
- Fast propagation delay for high-speed signal processing
- Separate output supply pin for flexible logic interfacing
Applications
- Analog-to-digital converter front ends
- Threshold detection circuits
- Window comparators
Procurement Notes
Verify the package type matches CDIP-8 specifications. Confirm the suffix 'AC' indicates the specific grade regarding offset voltage and speed parameters. Ensure the manufacturer source is authorized or reputable, as this component may be available through secondary distributors like Rochester Electronics. Check for lead-free compliance if required by assembly standards.
Selection Notes
Select this component when low input offset voltage is critical for accuracy. The separate output supply allows optimization for different load conditions without affecting the input stage. Consider the ceramic package for environments requiring hermetic sealing or high thermal stability compared to plastic alternatives.
Part Context
This part belongs to the LT10xx series of precision operational amplifiers and comparators from Linear Technology, now part of Texas Instruments. The series is known for high performance and reliability in industrial and instrumentation applications. The ACJG variant specifically denotes the ceramic DIP package with the A-grade performance specifications.
Replacement Considerations
LT1011AJG: Higher precision grade with lower offset voltage. LT1011CN8: Plastic DIP alternative with potentially different thermal and mechanical properties. Verify pin compatibility and parameter tolerances before substitution.
