MCP632-E/SN - Dual 24MHz R-R Op Amp | Microchip Technology
部品番号: MCP632-E/SN ✓ 生産中MCP632-E/SN 概要
An operational amplifier is a voltage-feedback amplifier used to amplify, buffer, filter, or compare analog signals. The MCP632 belongs to the operational-amplifier hierarchy, where its rail-to-rail output stage allows the output voltage to approach the supply rails while maintaining a 24 MHz bandwidth. This makes the device suitable for signal-conditioning stages that require faster settling than general-purpose low-power amplifiers provide.
Key performance features include a 24 MHz gain-bandwidth product and a 10 V/µs typical slew rate. The typical 1 MHz noise density is 10 nV/√Hz, while the typical short-circuit current is 70 mA. The dual-circuit configuration provides two independent amplifiers in one 8-SOIC package, reducing board area compared with two separate single operational amplifiers.
The MCP63x family combines high gain bandwidth with relatively high output short-circuit capability. Because the MCP632-E/SN is packaged in 8-SOIC, it can be placed on conventional surface-mount analog boards and routed with standard dual-amplifier layouts. Its rail-to-rail output improves usable output range in low-voltage systems where output headroom is limited.
Typical uses include audio preamplification, sensor signal conditioning, active filtering, comparator-style threshold circuits, and general analog signal conditioning. The 24 MHz bandwidth is particularly useful for higher-frequency sensor interfaces and low-level signal chains. Designers should still account for input common-mode limits, output drive, noise, and stability when connecting capacitive loads.
For layout, place input and output decoupling capacitors close to their corresponding pins and avoid routing sensitive input traces beside high-current outputs. Use a solid ground reference and assess gain-bandwidth and phase-margin requirements when driving capacitive or highly capacitive sensor networks. Stable feedback-network placement is especially important at the device's relatively high bandwidth.
This product data combines manufacturer and distributor specifications with focused engineering guidance, application analysis, package information, and verified replacement context. It helps engineers evaluate MCP632-E/SN for compact, high-speed dual analog signal-conditioning designs and compare the available drop-in option without obscuring the distinctions between amplifier families.

主な用途
MCP632-E/SN の用途: 6 件s: Sensor Signal Conditioning, Audio Preamplification, Active Filtering, Comparator-Style Threshold Detection, Industrial Data Acquisition, Portable and Battery-Powered Electronics.
Sensor Signal Conditioning
The MCP632-E/SN fits sensor front ends that require more bandwidth than a general-purpose low-power amplifier can provide. Its 24 MHz typical gain-bandwidth product and 10 V/µs typical slew rate preserve signal amplitude and phase margin across higher-bandwidth sensor outputs. The dual 8-SOIC implementation allows separate channels to handle a sensor signal and its reference, filter, or diagnostic path. Because the output is rail-to-rail, the amplifier can use more of the available output range in compact low-voltage systems. Designers should still confirm input common-mode range, output swing, noise, and sensor capacitive loading in the manufacturer electrical tables.
Audio Preamplification
The MCP632-E/SN is appropriate for low-level audio preamplification stages requiring a 24 MHz typical gain-bandwidth product and 10 V/µs typical slew rate. These characteristics provide bandwidth for source signals beyond the audible range and help limit large-signal distortion in the active gain stage. Its dual-channel package can support left and right channels or a stereo signal plus a monitoring path. The rail-to-rail output helps maximize signal swing in portable and low-voltage equipment. In practice, the input network must avoid excessive noise, and the layout should keep the feedback components close to the amplifier pins to preserve stability across the full audio bandwidth.
Active Filtering
The MCP632-E/SN is well suited to active filter stages that need a higher closed-loop bandwidth than basic precision amplifiers. A 24 MHz typical gain-bandwidth product gives designers margin for moderate-gain sections, while the 10 V/µs typical slew rate supports larger signal transitions. The two amplifier channels can implement a cascaded second-order section or build a two-stage filter in one 8-SOIC package. Component tolerances and the op-amp gain-bandwidth interaction determine the actual response. PCB placement should minimize parasitic capacitance around high-impedance nodes and keep the feedback loop compact to reduce oscillation risk.
Comparator-Style Threshold Detection
The MCP632-E/SN can support threshold-detection and comparator-style functions where fast output transitions and short-circuit capability are important. Its 10 V/µs typical slew rate enables rapid voltage changes, while the reported 70 mA typical short-circuit current provides greater output-drive capability than many low-power comparators. The rail-to-rail output helps the result approach the available supply limits. For dependable detection, review input offset voltage, common-mode range, propagation behavior, and output logic levels in the manufacturer documentation. A small amount of positive feedback may improve switching speed, but the feedback network and noise margin should be evaluated carefully.
Industrial Data Acquisition
The MCP632-E/SN fits dual-channel industrial data-acquisition front ends that amplify sensor or transducer signals before sampling. Its 24 MHz typical gain-bandwidth product supports conditioning of faster-changing inputs, and the 10 V/µs typical slew rate reduces the risk of large-signal limiting. Two channels in one 8-SOIC package simplify routing for differential or related signals. The rail-to-rail output maximizes usable swing in systems with constrained supply headroom. Industrial designs should still assess noise, offset, bias current, common-mode limits, and long-term drift for the selected temperature grade before establishing measurement accuracy.
Portable and Battery-Powered Electronics
The MCP632-E/SN can be used in portable electronics where a rail-to-rail output, two amplifier channels, and a compact 8-SOIC package help conserve board area. Its stated family operation from 1.8 V to 5.5 V supports low-voltage systems, while the 24 MHz gain-bandwidth product provides useful signal-conditioning bandwidth. Rail-to-rail output operation increases usable signal range without requiring a higher supply. Battery designs should compare each channel's operating current against the expected duty cycle because amplifier activity affects energy consumption. Confirm output loading, input bias current, sleep requirements, and shutdown strategy in the device specifications before selecting the amplifier.

設計ノート
Place input, output, and supply decoupling components directly beside their associated pins, with the ground return forming a short path. Keep the feedback network compact and separate high-impedance input traces from output and supply paths. The 24 MHz gain-bandwidth product makes board-induced feedback more consequential than it would be in a much slower precision amplifier.
Check capacitive loading before connecting sensors, cables, or long traces directly to the output. The 10 V/µs typical slew rate can expose a stability issue that remains hidden at low frequencies. If the source has significant capacitance, add an isolation resistor close to the output and verify the resulting response with the final load and board layout.
Calculate worst-case amplifier dissipation from the actual supply voltage, channel quiescent current, and load current. Include startup and transient behavior when sizing the local supply network because two channels can draw additional current during rapid output transitions. Maintain the manufacturer-specified supply range and provide adequate headroom for the desired output swing.
Do not assume that every MCP63x-family dual amplifier is interchangeable merely because it uses a similar package. Confirm amplifier-channel pin assignments, input common-mode range, output swing, offset, bias current, and stability for MCP633-E/SN before treating it as a production replacement. Use the manufacturer pin-description table when assigning PCB nets.
