MCP6G02-E/SN

Overview

The MCP6G02-E/SN is a dual Selectable Gain Amplifier (SGA) from Microchip Technology, housed in an 8-pin SOIC package. It operates on a single supply voltage ranging from 1.8V to 5.5V and supports an extended temperature range of -40°C to +125°C. Each amplifier channel provides three fixed non-inverting gain selections: +1 V/V, +10 V/V, and +50 V/V, controlled via a dedicated GSEL input pin. The device features rail-to-rail input and output capabilities, low quiescent current consumption of 110 µA typical, and high bandwidth performance up to 900 kHz at +1 gain.

Feature Summary

• Features selectable gain architecture with three fixed non-inverting options (+1, +10, +50 V/V) controlled by a digital logic input
• Provides rail-to-rail input and output swing for maximum dynamic range in single-supply applications
• Optimized for low power consumption with typical quiescent current of 110 µA per amplifier
• Includes internal resistor ladder network eliminating the need for external precision gain-setting resistors

Applications

• A/D Converter Driver
• Industrial Instrumentation
• Bar Code Readers
• Metering
• Digital Cameras

Procurement Notes

Verify that the specific suffix 'E' corresponds to the industrial temperature grade (-40°C to +125°C) as defined in the official datasheet. Confirm the 'SN' designation indicates the 8-lead Small Outline Integrated Circuit (SOIC) package type. Ensure the component matches the exact part number MCP6G02-E/SN to guarantee correct dual-channel configuration and electrical specifications.

Selection Notes

Select this component when designing circuits requiring flexible gain adjustment without external passive components. It is suitable for battery-powered systems due to its low supply current and wide operating voltage range. Consider the bandwidth limitations at higher gains (+10 and +50 V/V) when processing high-frequency signals. Verify that the required gain switching speed meets the application's timing constraints.

Part Context

This component belongs to the MCP6G01/1R/1U/2/3/4 family of Selectable Gain Amplifiers. While the MCP6G01 offers a single channel in various packages, the MCP6G02 specifically integrates two independent amplifiers into a compact 8-pin footprint. This family utilizes CMOS technology to achieve low bias currents and high input impedance, distinguishing it from bipolar operational amplifiers.

Replacement Considerations

Direct functional replacements within the same family include the MCP6G01-E/SN for single-channel requirements or the MCP6G04-E/SO for quad-channel configurations. Cross-family replacement requires verifying gain selection methods, pinout compatibility, and electrical parameter alignment.
