MCP6S93-E/UN

Overview

The MCP6S93-E/UN is a dual-channel, single-supply analog Programmable Gain Amplifier (PGA) from Microchip Technology. It features an SPI interface for selecting gains ranging from +1 V/V to +32 V/V and switching between two input channels. The device supports rail-to-rail input and output operation with a supply voltage range of 2.5V to 5.5V. Key electrical specifications include a typical bandwidth of 1 to 18 MHz, low noise density of 10 nV/√Hz at 10 kHz, and a maximum DC gain error of ±1%. It operates within an extended temperature range of -40°C to +125°C.

Feature Summary

• Dual-channel input multiplexer with selectable gain settings via SPI
• Rail-to-rail input and output capability for single-supply applications
• Low offset voltage mismatch between channels
• Shutdown mode for power conservation

Applications

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

Procurement Notes

Verify the specific ordering suffix '-E/UN' corresponds to the MSOP-10 package and the industrial temperature grade (-40°C to +125°C). Confirm that the 'UN' designation aligns with the manufacturer's current packaging standards for this component. Ensure compatibility with system requirements regarding the 10-pin MSOP footprint and lead-free RoHS compliance before finalizing procurement.

Selection Notes

Select the MCP6S93-E/UN when a dual-channel PGA with SPI control is required. This part is suitable for applications needing flexible gain adjustment from +1 to +32 V/V. Consider its rail-to-rail I/O and low noise characteristics for precision signal conditioning. Verify that the 10-pin MSOP package fits the design constraints and that the extended temperature range meets environmental specifications.

Part Context

The MCP6S93 is part of the MCP6S9x family of single-supply, low-gain PGAs. While the MCP6S91 offers one channel and the MCP6S92 provides two channels in smaller packages, the MCP6S93 specifically utilizes a 10-pin MSOP package to accommodate its dual-channel architecture and additional SPI output pin for daisy-chaining capabilities.

Replacement Considerations

The MCP6S92 serves as a functional substitute if only one channel is utilized, provided the 8-pin package constraint is acceptable. The MCP6S91 is another alternative for single-channel designs. Ensure pinout compatibility and verify that the package type difference does not impact the PCB layout or mechanical assembly.
