MCP6S26T-I/SL

Overview

The MCP6S26T-I/SL is a six-channel programmable gain amplifier (PGA) from Microchip Technology, housed in a 14-pin SOIC package. It supports gains from +1 V/V to +32 V/V via an SPI interface. Key electrical parameters include a maximum input offset voltage of ±275 µV, a typical quiescent current of 1.0 mA, and a bandwidth ranging from 2 MHz to 12 MHz depending on the gain setting. The device operates on a single supply voltage between 2.5 V and 5.5 V.

Feature Summary

• Features an integrated multiplexer for selecting one of six analog input channels.
• Provides eight selectable gain settings ranging from +1 V/V to +32 V/V.
• Supports rail-to-rail input and output capabilities for single-supply operation.

Applications

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

Procurement Notes

Verify that the ordering suffix 'T/I/SL' corresponds to the tape-and-reel packaging format and industrial temperature range specifications. Confirm the manufacturer part number matches the required six-channel configuration. Ensure compatibility with the intended PCB footprint for the 14-lead SOIC package before finalizing procurement orders.

Selection Notes

Select this component when a multi-channel signal conditioning solution with digital gain control is required. It is suitable for applications needing low offset voltage and high bandwidth. Consider the specific gain requirements and channel count compared to other family members like the MCP6S21 or MCP6S28.

Part Context

This part belongs to the MCP6S21/2/6/8 family of single-ended, rail-to-rail, low-gain error programmable gain amplifiers. The family offers varying channel counts from one to eight, all sharing similar SPI-controlled interfaces and performance characteristics optimized for data acquisition and instrumentation tasks.

Replacement Considerations

Direct substitutes within the same family include MCP6S26-I/ST and MCP6S26-I/P, which share identical electrical specifications but differ in packaging type.

FAQ

Does the MCP6S26T-I/SL support daisy-chaining?

Yes, the device includes a serial output (SO) pin that facilitates daisy-chain configurations with other compatible devices.

What is the function of the VREF pin?

The VREF pin allows for external reference voltage adjustment, shifting the output voltage level relative to the selected input and gain.
