CA3280F3

Overview

The CA3280F3 is a dual operational transconductance amplifier (OTA) manufactured by Harris Corporation, part of the CA3280 family. It integrates two independent amplifiers within a single package, designed for high-speed signal processing applications. The device features a gain-bandwidth product of 9 MHz and a slew rate of 125 V/µs, enabling rapid response to input changes. It operates with a supply voltage range from 4 V to 30 V and includes an internal buffer output stage. The component supports operation across a temperature range of 0°C to 70°C and is available in a 16-pin DIP package.

Feature Summary

• Dual integrated operational transconductance amplifier architecture
• High-speed performance with 9 MHz gain-bandwidth product
• Internal buffer output stage for improved drive capability
• Wide single-supply voltage operation range

Applications

• Video signal processing circuits
• Voltage-controlled filters
• Analog multipliers and mixers
• Automatic gain control systems

Procurement Notes

Verify manufacturer origin as Harris Corporation or authorized successor. Confirm RoHS compliance status as original datasheets may indicate non-compliance. Check pinout compatibility if substituting into existing designs. Validate operating temperature range requirements against application environment specifications before procurement.

Selection Notes

Select this component for applications requiring high-speed analog signal processing with dual amplifier channels. Consider the 9 MHz bandwidth and 125 V/µs slew rate for video frequency applications. Ensure supply voltage stays within 4 V to 30 V limits. Evaluate thermal management needs for continuous operation at upper temperature extremes.

Part Context

The CA3280 series represents a legacy line of high-performance operational transconductance amplifiers originally developed by Harris Semiconductor. These devices were widely used in professional audio and video equipment due to their superior speed characteristics compared to standard op-amps. The F3 suffix typically denotes specific packaging or testing variations within the broader CA3280 product family.

Replacement Considerations

Direct replacements include CA3280A, CA3280AE, and OPA860. Verify pin compatibility and electrical parameter equivalence when substituting. Note that some alternatives may have different pin configurations or require circuit modifications.
