MCP6023-I/SN

Instrumentation, Op Amps, Buffer Amps Overview

The MCP6023-I/SN is a single-channel, rail-to-rail input/output operational amplifier from Microchip Technology. It operates on a single supply voltage ranging from 2.5V to 5.5V and features a typical gain-bandwidth product of 10 MHz with a slew rate of 7 V/µs. The device includes an integrated mid-supply voltage reference (VREF) and a Chip Select (CS) pin for power management. Electrical characteristics include a maximum input offset voltage of ±500 µV at industrial temperatures, low noise density of 8.7 nV/√Hz, and unity gain stability.

• Rail-to-rail input and output capability for maximum dynamic range
• Integrated mid-supply voltage reference (VREF)
• Chip Select (CS) pin enables low-power shutdown mode
• Unity gain stable with high open-loop gain

Instrumentation, Op Amps, Buffer Amps Applications

• Automotive systems
• Multi-pole active filters
• Audio processing circuits
• DAC buffer stages
• Medical instrumentation

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the package type matches the 'SN' suffix (SOIC-8). Confirm the temperature grade corresponds to the 'I' suffix (Industrial: -40°C to +85°C). Ensure the specific part number aligns with the required channel count and feature set, as other variants in the family may lack the VREF or CS pin.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single op amp with a built-in voltage reference and power-down control is required. It is suitable for applications needing rail-to-rail performance within a 2.5V to 5.5V supply range. Consider the MCP6021 if the Chip Select function is not needed, or the MCP6022 for dual-channel requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

The MCP6023 is part of the MCP6021/1R/2/3/4 family of high-performance, rail-to-rail input/output operational amplifiers. This family shares common electrical characteristics such as 10 MHz bandwidth and low noise, but varies in channel count and additional features like the Chip Select pin and internal voltage reference found in the MCP6023.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes within the same family include MCP6021-I/SN (without CS/VREF) or MCP6022-I/SN (dual channel). Cross-manufacturer replacements require matching GBWP, slew rate, supply voltage range, and package dimensions.

Instrumentation, Op Amps, Buffer Amps FAQ

What is the function of the VREF pin?

The VREF pin provides an unbuffered mid-supply voltage reference, equal to VDD/2, which is useful for biasing single-supply circuits.

How does the Chip Select (CS) pin affect operation?

Driving the CS pin high places the amplifier into a low-power shutdown mode, significantly reducing quiescent current. Driving it low returns the device to normal operation.
