MCP6S93T-E/UN

Overview

The MCP6S93T-E/UN is a dual-channel, single-supply Programmable Gain Amplifier (PGA) from Microchip Technology. It features an SPI interface for gain selection and channel multiplexing. The device supports gains from +1 V/V to +32 V/V with a bandwidth of 1 to 18 MHz. Key electrical parameters include a maximum input offset voltage of 4 mV, typical quiescent current of 1.0 mA, and operation within a supply voltage range of 2.5 V to 5.5 V. It operates over an extended temperature range of -40°C to +125°C and is housed in a 10-lead MSOP package.

Feature Summary

• Dual-channel analog inputs selectable via Serial Peripheral Interface
• Rail-to-rail input and output capability for single-supply applications
• Low input 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 'T-E/UN' corresponds to the tape-and-reel packaging format and the '-E' industrial temperature grade (-40°C to +125°C). Confirm that the 10-pin MSOP package matches the target PCB footprint. Ensure the design accounts for the serial output pin available on the MCP6S93 variant for daisy-chain configurations.

Selection Notes

Select this component when a dual-channel PGA with SPI control is required. The MCP6S93 provides two analog inputs compared to the single-channel MCP6S91. Consider the rail-to-rail I/O and low offset characteristics for precision signal conditioning. Verify that the 10-lead MSOP package is suitable for the assembly process and space constraints.

Part Context

This part belongs to the MCP6S91/2/3 family of single-ended, low-gain error programmable gain amplifiers. The MCP6S93 specifically denotes the two-channel version of the series. These devices are designed for high-speed, low-offset applications requiring flexible gain settings controlled digitally via SPI.

FAQ

Does the MCP6S93 have a digital output?

Yes, the MCP6S93 includes a Serial Output (SO) pin on the SPI interface, which facilitates daisy-chaining multiple devices.

What is the input offset voltage mismatch between the two channels?

The input offset voltage mismatch between channels CH0 and CH1 is ideally 0 µV.
