MCP6G02T-E/SN

Overview

The MCP6G02T-E/SN is a dual Selectable Gain Amplifier (SGA) manufactured by Microchip Technology, housed in an 8-pin SOIC package. It supports single-supply operation from 1.8V to 5.5V with a typical quiescent current of 110µA per amplifier. The device offers three fixed non-inverting gains: +1 V/V, +10 V/V, and +50 V/V, selected via the GSEL pin. Key electrical characteristics include a maximum input offset voltage of ±4.5mV at G=+1, a bandwidth ranging from 250kHz to 900kHz depending on gain, and rail-to-rail input and output capabilities.

Feature Summary

• Selectable Gain Architecture: Provides three fixed non-inverting gain options (+1, +10, +50 V/V) controlled by a digital logic input.
• Rail-to-Rail Performance: Features both rail-to-rail input and output stages for maximum dynamic range in single-supply applications.
• Low Power Consumption: Optimized for low quiescent current operation, typically 110µA per channel, suitable for battery-powered systems.
• High Input Impedance: Utilizes CMOS analog inputs with extremely low bias currents to minimize loading effects on signal sources.

Applications

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

Procurement Notes

Verify the specific suffix 'E' corresponds to the extended temperature range (-40°C to +125°C) as defined in the datasheet. Confirm the 'SN' suffix indicates the 8-lead Small Outline Integrated Circuit (SOIC) package type. Ensure compatibility with the required supply voltage range of 1.8V to 5.5V for your application design.

Selection Notes

Select this component when variable gain is required without external resistors. Compare bandwidth requirements against the specified 250kHz to 900kHz range based on the chosen gain setting. Consider the ±1% maximum DC gain error if high precision is needed. Verify that the 8-pin SOIC footprint fits the PCB layout constraints.

Part Context

This part belongs to the MCP6G01/1R/1U/2/3/4 family of Selectable Gain Amplifiers. While the MCP6G01 is a single-channel version, the MCP6G02 integrates two identical amplifiers in one package. Other variants like the MCP6G03 include a Chip Select pin for shutdown functionality, which is absent in the MCP6G02.

FAQ

How is the gain selected on the MCP6G02?

Gain selection is performed via the GSEL pin. A voltage near VDD/2 selects +1 V/V, a low voltage selects +10 V/V, and a high voltage selects +50 V/V.

Does the MCP6G02 support shutdown mode?

No, the MCP6G02 does not have a Chip Select (CS) pin. Only the MCP6G03 variant in this family includes the shutdown feature.
