CA3080E

Overview

The CA3080E is an operational transconductance amplifier (OTA) manufactured by Renesas Electronics Corporation. It features a differential input and a single-ended, push-pull, class A output with high output impedance. The device incorporates an amplifier bias input for gating or linear gain control, where transconductance is directly proportional to the bias current. Designed for the commercial temperature range of 0°C to 70°C, it utilizes an 8-lead PDIP package.

Feature Summary

• Operational transconductance architecture providing voltage-controlled current source functionality
• Adjustable power consumption via external amplifier bias current control
• High slew rate performance suitable for multiplexer and fast unity-gain voltage follower applications
• Flexible supply voltage operation across a wide dual-supply range

Applications

• Sample and hold circuits
• Multiplexers
• Voltage followers
• Function generators
• Comparators

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm the specific suffix 'E' denotes the commercial temperature grade (0°C to 70°C). Ensure proper electrostatic discharge handling procedures are followed during storage and assembly to prevent damage to the sensitive internal circuitry.

Selection Notes

Select this component when designing circuits requiring adjustable gain or high-speed switching capabilities. Consider the relationship between bias current and transconductance for precise signal processing. Evaluate thermal dissipation requirements based on the selected operating bias current and ambient temperature conditions within the specified commercial range.

Part Context
