MCP6275-E/MS

Instrumentation, Op Amps, Buffer Amps Overview

The MCP6275-E/MS is a dual operational amplifier manufactured by Microchip Technology, featuring a 2 MHz Gain Bandwidth Product and a typical quiescent current of 170 µA per amplifier. It operates on a single supply voltage ranging from 2.0V to 6.0V and supports rail-to-rail input and output swing. The device includes a Chip Select (CS) pin that enables low power mode operation. It is housed in an MSOP-8 package and is rated for an extended operating temperature range from -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Features a Chip Select (CS) pin that places the device into a low power mode when activated.
• Supports rail-to-rail input and output voltage swings for maximum dynamic range.
• Utilizes advanced CMOS process technology for low cost and low power consumption.
• Designed with internal circuitry to prevent phase reversal when input voltages exceed supply rails.

Instrumentation, Op Amps, Buffer Amps Applications

• Automotive systems
• Portable equipment
• Photodiode amplifiers
• Analog filters

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'E' corresponds to the required extended temperature grade (-40°C to +125°C). Confirm the 'MS' package designation matches the MSOP-8 footprint requirements for your PCB layout. Ensure the Chip Select functionality aligns with system power management strategies, as this variant differs from standard dual op amps without CS pins.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the MCP6275-E/MS when cascaded dual op amp configurations are needed within an 8-pin package. This part is suitable for applications requiring low supply voltage operation down to 2.0V. Consider the 170 µA quiescent current and 2 MHz bandwidth for general-purpose signal conditioning tasks where power efficiency is a priority.

Instrumentation, Op Amps, Buffer Amps Part Context

The MCP6275 belongs to the MCP6271/1R/2/3/4/5 family of operational amplifiers. Unlike the standard MCP6272, the MCP6275 integrates a Chip Select feature by internally connecting the output of the first amplifier to the non-inverting input of the second. This architecture allows for power-down control while maintaining a compact 8-pin form factor.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the Chip Select pin affect the MCP6275's operation?

When the Chip Select (CS) pin is pulled high, the device enters a low power mode where the supply current drops significantly, and the amplifier outputs enter a high-impedance state. Pulling CS low enables normal operation.

What is the unique internal connection of the MCP6275?

The MCP6275 features an internal connection where the output of Op Amp A is directly connected to the non-inverting input of Op Amp B. This shared pin serves as the non-inverting input for the second stage and allows for the inclusion of the Chip Select pin in an 8-pin package.
