CA3160T

Overview

The CA3160T is a BiMOS operational amplifier manufactured by Intersil, now distributed by Rochester Electronics. It features a MOSFET input stage and a CMOS output stage, providing high input impedance and low bias current. The device offers a gain-bandwidth product of 4 MHz and a slew rate suitable for general-purpose analog signal processing applications.

Feature Summary

• BiMOS technology combining MOSFET inputs with CMOS outputs
• High input impedance characteristic inherent to the MOSFET input stage
• Low input bias current reducing loading effects on source circuits

Applications

• Precision integrator circuits requiring minimal input current drift
• Sample-and-hold amplifiers utilizing fast settling times
• High-impedance buffer stages in sensor interface designs
• Active filter implementations within audio or instrumentation systems

Procurement Notes

Verify the manufacturer origin as Intersil Corporation when sourcing from Rochester Electronics. Confirm the package type corresponds to the T suffix designation. Ensure the component meets the specific environmental and electrical standards required for the target application before integration.

Selection Notes

Select this component for designs prioritizing high input impedance over ultra-low noise performance. Compare against standard bipolar op-amps where bias current reduction is critical. Evaluate the 4 MHz bandwidth against system frequency requirements to ensure adequate phase margin and stability in feedback configurations.

Part Context

This part belongs to the CA3160 family of BiMOS operational amplifiers. It shares architectural similarities with other Intersil BiMOS devices but is distinct in its specific 4 MHz bandwidth specification. The T suffix typically denotes a specific thermal or packaging variant within the broader product line.

Replacement Considerations

Official substitute part numbers are not confirmed in the available documentation. Cross-reference with other BiMOS op-amps only if electrical parameters such as input bias current and bandwidth are strictly matched. Verify pin compatibility and package dimensions before considering alternative manufacturers.
