Overview
The CA3290T is a dual comparator manufactured by Harris Corporation, housed in an 8-pin metal can (MBCY8) package. It features a maximum input offset voltage of 20,000 µV and a typical response time of 200 ns. The device operates within a temperature range of -55 °C to 125 °C and supports supply voltages of 5 V or ±15 V. It has a maximum bias current of 0.00005 µA at 25°C and a slew rate of 3.5 mA.
Feature Summary
- Dual comparator configuration with high-speed response capabilities
- Military-grade reliability with MIL-STD-883 Class B screening
- Low input bias current for precision signal comparison
Applications
- High-speed analog-to-digital conversion interfaces
- Precision voltage monitoring circuits
- Waveform generation and shaping systems
Procurement Notes
Verify the specific manufacturer source, as RCA originally produced this component before Harris acquired relevant assets. Confirm that the MBCY8 metal can package matches the required form factor for the application. Ensure the MIL-STD-883 Class B qualification meets the environmental standards for the intended deployment environment.
Selection Notes
Select this component when military-grade reliability and fast switching speeds are required in a compact metal package. Consider the 200 ns response time for high-frequency applications. Verify compatibility with the specified 5 V or ±15 V power supplies and ensure the operating temperature range suits the installation site.
Part Context
The CA3290T belongs to the Harris/RCA family of linear integrated circuits, specifically designed for analog signal processing. As a dual comparator, it provides two independent comparison functions in a single package. The use of a metal can package indicates its design for harsh environments requiring robust physical protection and thermal stability.
Replacement Considerations
Check for direct cross-references from Harris or Raytheon datasheets. Verify pinout compatibility if substituting with other dual comparators in an 8-pin metal can package.
