CA3080AF

Overview

The CA3080AF is a high-performance operational transconductance amplifier (OTA) manufactured by Rochester Electronics. It features a gatable-gain block architecture with differential inputs and a single-ended, push-pull, class A output. The device includes an amplifier bias input for gating or linear gain control. Key electrical characteristics include a slew rate of 50V/µs in unity gain compensated configuration, adjustable power consumption ranging from 10µW to 30µW, and a flexible supply voltage range of ±2V to ±15V. The transconductance is directly proportional to the bias current.

Feature Summary

Operational transconductance amplifier concept with differential input and single-ended push-pull class A output
Amplifier bias input enables gating or linear gain control functionality
High output impedance with transconductance directly proportional to amplifier bias current

Applications

Sample and hold circuits
Analog multipliers
Multiplexers
Comparators
Voltage followers

Procurement Notes

Verify the specific suffix AF against official manufacturer documentation to confirm package type and temperature grade. Ensure compatibility with system requirements for supply voltage and bias current settings before procurement.

Selection Notes

Select this component for applications requiring precise analog signal processing where variable gain control is necessary. Consider the flexibility of the supply voltage range and the ability to adjust power consumption based on the specific bias current applied to the device.

Part Context

The CA3080 series utilizes the unique operational-transconductance amplifier concept described in Application Note AN6668. It is designed for high-performance analog signal processing tasks, offering tight transconductance spread and extended linearity across three decades of operation.

FAQ

How is the gain of the CA3080 controlled?

The gain is fully adjustable and depends on the transconductance (gM) and load resistance (RL). The transconductance itself is directly proportional to the amplifier bias current (IABC), allowing for linear gain control via the bias input.
