CA5130AM

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.

Feature Summary

• MOSFET input stage provides very high input impedance and very low input current
• CMOS output stage permits signal swing to either or both supply rails
• Common mode input voltage range includes the negative supply rail

Applications

• Ground referenced single supply amplifiers
• Fast sample-hold amplifiers
• Long duration timers and monostables
• High input impedance comparators ideal for digital CMOS interface

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.

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.

Part Context

The CA5130 series integrates PMOS field effect transistors in the input stage to achieve exceptional speed performance and high input impedance. This design allows operation down to V+ = 4.5V for open-loop gain and supports ±7.5V operation. The device is designed for use in systems utilizing +5V supplies.
