MCP6023-I/P - 10 MHz Rail-to-Rail Op Amp | Microchip Technology
MPN: MCP6023-I/P ✓ ActiveMCP6023-I/P Overview
The MCP6023 belongs to the operational-amplifier hierarchy: it is a general-purpose amplifier, a voltage-feedback signal-conditioning amplifier, and ultimately a semiconductor active device. Rail-to-rail input operation allows the amplifier to sense signals close to either supply rail, while rail-to-rail output swing improves usable output range in low-voltage systems. These characteristics are useful when the signal source operates from a 3.3 V or 5 V rail and the available signal headroom is limited.
The MCP6023-I/P combines a typical operating current of 1.0 mA with a typical gain-bandwidth product of 10 MHz. Its typical slew rate is 7 V/us, and its voltage-noise density is 8.7 nV/Hz at 10 kHz. The manufacturer describes a typical input offset voltage below 0.5 mV, with the industrial-grade -I/P version providing a maximum offset voltage of 500 uV according to distributor specification data. These figures make it suitable for general signal conditioning rather than precision instrumentation applications requiring very low offset or drift.
Typical uses include low-voltage sensor interfaces, audio preamplifier stages, active filters, ADC driver blocks, and general-purpose buffering. Because the output can approach the supply rails, the device is also useful in mixed-signal systems where a conventional amplifier would clip before the system ADC or downstream converter reaches its usable range. The shutdown feature can also reduce supply consumption when the signal chain does not need to remain active.
When designing around the MCP6023-I/P, verify the datasheet pinout and the shutdown-pin logic before layout. Because this is a bipolar-package device intended for through-hole assembly, confirm available PCB footprint, insertion tooling, and connector clearance. Decoupling capacitors should be placed close to the supply pins, and the amplifier should be configured with stable feedback values for the intended gain and load.
This page combines manufacturer and distributor specifications, package information, sourcing links, application guidance, and replacement considerations. It is intended to help engineers confirm electrical suitability, package compatibility, and lifecycle availability before placing the MCP6023-I/P into a production bill of materials.

Typical Applications
MCP6023-I/P is suitable for 6 applications: 3.3 V Sensor Signal Conditioning, Audio Preamplifier and Buffer, Active Filtering and Equalization, ADC Driver and Interface Buffer, Industrial Control Signal Conditioning, Battery-Powered Portable Instrument.
3.3 V Sensor Signal Conditioning
The MCP6023-I/P fits low-voltage sensor conditioning because its 2.5 V minimum supply and rail-to-rail input operation reduce common-mode constraints when a sensor output sits close to either rail. The single amplifier can buffer or amplify the sensor signal before conversion by an ADC. Its 1.0 mA typical operating current helps preserve battery life in portable instrumentation, while the 10 MHz typical gain-bandwidth product provides margin for moderate-gain stages. Design checks should include sensor output impedance, cable capacitance, noise bandwidth, and the MCP6023 stability requirements at the selected closed-loop gain.
Recommended
Audio Preamplifier and Buffer
The MCP6023-I/P is appropriate for general audio preamplifier and buffer stages because it combines a 7 V/us typical slew rate with rail-to-rail output capability. This allows useful signal swing in low-voltage audio systems and avoids relying on the amplifier output for clipping close to the supply rail. The 8.7 nV/Hz typical voltage-noise density at 10 kHz provides a defined starting point for audio noise budgeting. In microphone or line-input designs, verify source impedance, input capacitance, gain-bandwidth stability, and the required output coupling network before production release.
Recommended
Active Filtering and Equalization
The MCP6023-I/P can implement active filters and equalization stages where its 10 MHz typical gain-bandwidth product provides useful loop gain above audio and control-signal frequencies. The low 1.0 mA typical operating current supports compact analog modules, and the rail-to-rail output can improve dynamic range in low-supply designs. Component tolerances and the amplifier's actual gain-bandwidth response determine the filter's usable corner frequency and phase margin. Simulate the closed-loop network with realistic loading and verify stability against the device's recommended feedback and capacitive-load conditions.
Recommended
ADC Driver and Interface Buffer
The MCP6023-I/P can buffer a sensor or mixer output into an ADC input when the required bandwidth is moderate. Its 10 MHz typical gain-bandwidth product and 7 V/us typical slew rate help preserve signal amplitude at higher frequencies, while rail-to-rail output operation supports ADC inputs operating from a low-voltage rail. The design must account for ADC settling requirements, sampling-capacitor kickback, and amplifier stability with capacitive loading. Check whether the application's required settling time, noise, and full-scale range exceed the MCP6023's specified operating limits.
Recommended
Industrial Control Signal Conditioning
The MCP6023-I/P is suitable for industrial control modules that condition low-level analog signals near a 3.3 V or 5 V supply. The industrial-grade -I/P ordering option, typical 1.0 mA operating current, and rail-to-rail input/output behavior help meet both supply and signal-range constraints. The amplifier can scale sensor outputs, buffer control-loop signals, or drive downstream ADC circuitry. For safety-critical or long-life industrial equipment, confirm the complete temperature rating, isolation strategy, protection-network design, and production lifecycle status rather than relying on the general-purpose description alone.
Recommended
Battery-Powered Portable Instrument
The MCP6023-I/P suits battery-powered measurement modules where every milliamp of continuous supply current can affect run time. Its 1.0 mA typical operating current is combined with a shutdown or chip-select function in the family, allowing the amplifier to be disabled when measurements are not active. The 2.5 V minimum supply supports low-voltage designs, and rail-to-rail input and output operation improves usable range. Validate leakage currents, shutdown behavior, startup transients, and the sensor's own power consumption to determine whether the complete measurement chain meets its duty-cycle energy budget.

Key Differentiators
- Rail-to-rail input and output in a through-hole package (vs MCP6023-I/SN)
- Low operating current for a 10 MHz amplifier (vs MCP6023-I/ST)
- Industrial-grade ordering option with specified offset limit (vs MCP6023-I/SN)
Design Notes
Place the supply bypass capacitor as close as practical to the V+ and V- pins, and route the amplifier ground connection directly to the device ground pin rather than through a long shared path. For the 8-DIP footprint, confirm the 0.300 inch, 7.62 mm lead pitch against the PCB drawing and provide adequate clearance for through-hole soldering and connector access.
Do not substitute an 8-SOIC MCP6023 variant onto an PDIP footprint. MCP6023-I/SN and MCP6023T-I/SN are surface-mount alternatives with different footprints and assembly requirements, while MCP6023-I/ST is also a different package family. Any proposed replacement must have the same 8-DIP footprint, pin function, supply range, shutdown behavior, and acceptable electrical parameters before it is treated as drop-in.
Check the closed-loop gain against the MCP6023's recommended operating region, especially with capacitive sensor cables or ADC sampling inputs. Add isolation resistors between the amplifier and capacitive loads when needed, and keep feedback traces short. For low-level sensor work, calculate the input-referred noise over the actual measurement bandwidth and include the sensor, bias-resistor, and reference noise in the system budget.
Use the family shutdown or chip-select function to disable the amplifier during inactive measurement intervals, but confirm the control-pin logic and state current from the manufacturer datasheet. Low-voltage rails do not eliminate transient concerns: verify startup overshoot, input clamping during shutdown, and the behavior of external sensors connected to the amplifier pins.
Compliance Information
The supplied verified data identifies the MCP6023-I/P as an industrial-grade 8-DIP operational amplifier but does not provide explicit RoHS, REACH, lead-free, halogen-free, conflict-minerals, or AEC-Q100 statements. These fields are therefore left as unknown or not applicable rather than assumed.
