Overview
The CA5420AM is a single-channel general-purpose operational amplifier manufactured by Renesas Electronics Corporation. It utilizes BiMOS technology to achieve low input bias current and low supply voltage operation. The device features a gain-bandwidth product of 500 kHz, a slew rate of 0.5 V/µs, and an input offset voltage of 2 mV. It operates with a supply voltage range from 2 V to 20 V and draws 450 µA of supply current. The output provides rail-to-rail swing capabilities. The component is housed in an 8-SOIC package and supports a junction temperature range from -55°C to 125°C.
Feature Summary
- BiMOS technology integration for low input bias current performance
- Rail-to-rail output swing capability for maximum dynamic range
- Low supply voltage operation suitable for battery-powered systems
Applications
- Instrumentation signal conditioning circuits
- Buffer amplification stages
- Low-power sensor interface applications
Procurement Notes
Verify the obsolete status of the CA5420AM before procurement planning. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate that the direct replacement CA5420AMZ meets all electrical specifications for the design. Ensure supply chain sources provide authentic components from authorized distributors or verified secondary markets.
Selection Notes
Select this component for designs requiring low input bias current and rail-to-rail output within a single-channel configuration. Consider the 500 kHz bandwidth and 0.5 V/µs slew rate for moderate-speed signal processing tasks. Evaluate the 8-SOIC package constraints against PCB layout requirements. Assess the -55°C to 125°C operating temperature range against environmental conditions.
Part Context
The CA5420AM belongs to the CA5420 family of low-power operational amplifiers. It is a legacy product from Intersil, now part of Renesas Electronics. The device represents a BiMOS architecture combining bipolar and CMOS technologies. It serves as a foundational analog building block for precision applications requiring low power consumption and high input impedance characteristics.
Replacement Considerations
The CA5420AMZ is listed as a direct substitute. Verify pinout compatibility and electrical parameter alignment between the AM and AMZ suffixes before implementation.
