MCP603T-I/ST

Instrumentation, Op Amps, Buffer Amps Overview

The MCP603T-I/ST is a single-channel operational amplifier from the Microchip MCP601/2/3/4 family, featuring Chip Select functionality. It operates on a single supply of 2.7V to 6.0V with rail-to-rail output and input ranges including ground. Key electrical parameters include a typical gain bandwidth product of 2.8 MHz, unity-gain stability, and a quiescent current of 230 µA per amplifier. The device supports industrial temperature ranges (-40°C to +85°C) and utilizes advanced CMOS technology for low bias current and high open-loop gain.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Integrated Chip Select (CS) pin enables low-power shutdown mode by placing the amplifier in a high-impedance state.
• Rail-to-rail output swing capability allows operation close to both supply rails under specified load conditions.
• Input common-mode voltage range extends below ground, facilitating single-supply applications.
• Unity-gain stable design ensures reliable performance across general-purpose configurations.

Instrumentation, Op Amps, Buffer Amps Applications

• Portable equipment requiring low power consumption
• A/D converter driver circuits
• Photo diode pre-amplifiers
• Analog filters and data acquisition systems

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature range (-40°C to +85°C) as defined in the datasheet. Confirm the 'ST' suffix indicates the SOIC-8 package type. Ensure the 'T' suffix matches the required tape-and-reel packaging format for automated assembly processes.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single amplifier with power-down control is required. The MCP603 offers lower quiescent current compared to bipolar counterparts while maintaining sufficient bandwidth for signal conditioning. Consider the SOT-23-6 or SOIC-8 packages based on board space constraints and thermal requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MCP601/1R/2/3/4 series of low-power CMOS operational amplifiers. The family includes single, dual, and quad configurations. The MCP603 specifically adds a Chip Select feature not present in the standard MCP601, allowing for system-level power management without external switching components.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional substitutes within the same family include the MCP601 for non-shutdown applications. For different package options, consider the MCP603-I/SN (SOIC-8 tube) or MCP603-E/CH (SOT-23-6). Verify temperature range compatibility if replacing an Extended grade part.
