CA5130AM

Instrumentation, Op Amps, Buffer Amps Overview

The CA5130AM is a monolithic integrated circuit operational amplifier combining CMOS and bipolar transistor advantages. It features a MOSFET input stage providing very high input impedance and low input current, suitable for single-supply applications. The device operates with +5V supplies in microprocessor or logic systems, allowing common mode input voltage down to 0.5V below the negative supply rail. The CMOS output stage permits signal swing to either or both supply rails.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer designation carefully, as Intersil Corporation acquired Harris Semiconductor assets. Confirm that the 'A' suffix denotes the full military temperature range guarantee. Ensure the datasheet references align with the specific CA5130A specifications rather than generic CA5130 data.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring high input impedance and compatibility with +5V logic systems. The ability to operate with input voltages below the negative supply rail makes it suitable for single-supply designs. Verify that the military temperature range meets environmental requirements.

Instrumentation, Op Amps, Buffer Amps Part Context
