MCP6S92T-E/MSVAO

Overview

The MCP6S92T-E/MSVAO is a dual-channel, single-supply Programmable Gain Amplifier (PGA) from Microchip Technology. It features an integrated input multiplexer selectable via a Serial Peripheral Interface (SPI). The device supports gains ranging from +1 V/V to +32 V/V with low gain error and rail-to-rail input/output capability. It operates on a single supply voltage between 2.5V and 5.5V, drawing a typical quiescent current of 1.0 mA. The component is qualified for automotive applications under AEC-Q100 standards and functions reliably across an extended temperature range of -40°C to +125°C.

Feature Summary

• Dual-channel architecture with internal multiplexer for selecting between two analog inputs
• Programmable gain control via SPI interface supporting eight discrete gain settings
• Rail-to-rail input and output operation compatible with single-supply configurations
• Integrated shutdown mode accessible through the serial interface to minimize power consumption

Applications

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

Procurement Notes

Verify that the specific suffix 'VAO' corresponds to the Automotive Grade qualification as indicated in the product description. Confirm the package type matches the MSOP-8 specification required for the design. Ensure the operating environment stays within the specified -40°C to +125°C temperature range. Check for any specific handling requirements related to moisture sensitivity levels defined in the datasheet.

Selection Notes

Select this component when a dual-channel signal path requires programmable amplification without external resistor networks. The integrated multiplexer simplifies board layout compared to discrete solutions. Consider the rail-to-rail performance if the application demands maximum dynamic range near the supply rails. Verify that the SPI interface timing constraints align with the host microcontroller capabilities.

Part Context

This part belongs to the MCP6S91/2/3 family of single-ended, low-gain Programmable Gain Amplifiers. While the MCP6S91 offers a single channel and the MCP6S93 provides two channels in a different package, the MCP6S92 specifically delivers dual-channel functionality in an 8-pin MSOP form factor. All variants share identical electrical characteristics and SPI control logic.

Replacement Considerations

Direct functional substitutes within the same family include the MCP6S91T-E/MSVAO for single-channel needs or the MCP6S93T-E/MSVAO for alternative packaging. Cross-family replacements require careful evaluation of gain accuracy, bandwidth, and pin compatibility.
