MCP6G04-E/SL

Overview

The MCP6G04-E/SL is a quad selectable gain amplifier from Microchip Technology, housed in a 14-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. The device features rail-to-rail input and output capabilities with four independent channels. Each channel allows gain selection between +1 V/V, +10 V/V, and +50 V/V via a dedicated Gain Select pin. Key electrical specifications include a maximum input offset voltage of 4.5 mV at G=+1, a typical quiescent current of 110 µA per amplifier, and a bandwidth varying from 250 kHz to 900 kHz depending on the selected gain.

Feature Summary

• Features three fixed non-inverting gain options (+1, +10, +50 V/V) selectable via individual digital control pins for each amplifier channel.
• Provides rail-to-rail input and output performance optimized for low-voltage single-supply applications.
• Delivers high input impedance with extremely low input bias current, minimizing loading effects on signal sources.

Applications

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

Procurement Notes

Verify the specific suffix 'E/SL' corresponds to the industrial temperature grade (-40°C to +125°C) and SOIC-14 packaging configuration. Confirm that the ordering information matches the quad-channel variant rather than single or dual versions within the same family. Ensure compatibility with the required gain select logic levels relative to the system supply voltage before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring multiple independently configurable amplification stages without external resistors. It is suitable for battery-powered systems due to its low quiescent current consumption. Consider the bandwidth limitations at higher gains (+50 V/V) when processing high-frequency signals. Verify that the load requirements fall within the specified output swing capabilities for the chosen supply voltage.

Part Context

This part belongs to the MCP6G01/1R/1U/2/3/4 family of Selectable Gain Amplifiers (SGAs). While other variants offer single or dual channels in different packages like SOT-23 or MSOP, the MCP6G04 specifically provides four channels in a 14-pin SOIC or TSSOP footprint. This family is designed to simplify circuit design by integrating precision resistor ladders internally.

Replacement Considerations

Direct functional substitutes within the same Microchip family include MCP6G01, MCP6G02, and MCP6G03, though channel counts and package types differ. Cross-manufacturer replacements require matching the quad topology, selectable gain functionality, and rail-to-rail specifications.
