MCP6S26-I/SL

Overview

The MCP6S26-I/SL is a six-channel analog Programmable Gain Amplifier (PGA) from Microchip Technology, housed in a 14-pin SOIC package. It features an integrated multiplexer selectable via a Serial Peripheral Interface (SPI). The device supports gains ranging from +1 V/V to +32 V/V with a maximum input offset voltage of ±275 µV and a typical bandwidth between 2 MHz and 12 MHz. Operating on a single supply voltage from 2.5V to 5.5V, it provides rail-to-rail input and output capabilities.

Feature Summary

• Six-channel analog input multiplexer controlled by SPI interface
• Programmable gain selection from +1 V/V to +32 V/V
• Rail-to-rail input and output operation for single-supply applications
• Low input offset voltage and low noise characteristics

Applications

• A/D Converter Driver
• Multiplexed Analog Applications
• Data Acquisition Systems
• Industrial Instrumentation
• Medical Instrumentation

Procurement Notes

Verify the specific suffix 'I/SL' corresponds to the industrial temperature range (-40°C to +85°C) and SOIC-14 package configuration. Confirm that the ordering code matches the six-channel variant within the MCP6S26 family. Ensure compatibility with standard SPI logic levels and single-supply voltage requirements during integration.

Selection Notes

Select this component when multiple analog signals require amplification and digitization using a shared ADC. The integrated multiplexer reduces external switching hardware. Verify that the required gain settings align with the available discrete steps. Consider the bandwidth limitations at higher gain settings for high-frequency signal processing needs.

Part Context

This part belongs to the MCP6S21/2/6/8 family of programmable gain amplifiers. The MCP6S26 specifically provides six input channels, distinguishing it from the one-channel MCP6S21, two-channel MCP6S22, and eight-channel MCP6S28 variants. All family members share similar electrical characteristics and SPI control protocols.

Replacement Considerations

Direct substitutes include other parts within the MCP6S21/2/6/8 family, such as the MCP6S26T-I/ST or MCP6S26-E/SP, provided pinout and package compatibility are verified. Cross-family replacements require careful evaluation of gain accuracy, bandwidth, and supply voltage specifications.
