CA3493AS

Overview

The CA3493AS is a single-channel BiMOS precision operational amplifier manufactured by Harris Corporation. It features a gain bandwidth product of 1.2 MHz and a slew rate of 0.25V/µs. The device exhibits an input bias current of 10 nA and a voltage input offset of 140 µV. Supply current consumption is specified at 2.3 mA. It is housed in an 8-pin SOIC surface-mount package and operates within a temperature range of -25°C to 85°C.

Feature Summary

• Combines MOS and bipolar transistor technologies on a single monolithic chip for precision performance.

Applications

• Precision instrumentation circuits
• General purpose amplification tasks

Procurement Notes

Verify the manufacturer designation, as Harris Corporation assets were acquired by L3Harris Technologies. Confirm the specific suffix 'AS' corresponds to the SOIC-8 package and commercial temperature range. Ensure datasheet revisions match the required specifications for input bias and offset voltage before finalizing procurement orders.

Selection Notes

Select this component when a low-power, general-purpose op-amp with BiMOS technology is required. The 1.2 MHz bandwidth and 0.25V/µs slew rate suit moderate-speed applications. The 8-pin SOIC package facilitates surface-mount assembly. Verify that the 2.3 mA supply current fits the system power budget constraints.

Part Context

This part belongs to the CA3493 series of BiMOS precision operational amplifiers. The series integrates the advantages of both MOS and bipolar transistors. The CA3493AS variant specifically denotes the surface-mount SOIC-8 packaging option. It serves as a general-purpose solution for analog signal processing tasks requiring moderate precision.

Replacement Considerations
