MCP602-E/ST - Dual 2.8MHz CMOS Op Amp | Microchip Technology
부품 번호: MCP602-E/ST ✓ 활성MCP602-E/ST 개요
An operational amplifier, or op amp, is a high-gain differential amplifier whose open-loop behavior is controlled by negative feedback. Within the broader semiconductor hierarchy, an op amp is an analog amplifier IC used in signal conditioning, sensing, filtering, buffering, and control systems. Rail-to-rail output swing allows the MCP602 output to approach its supply rails more closely than a conventional output stage, which is useful when the available signal headroom is limited.
The MCP602 uses Microchip's advanced CMOS technology to provide low bias current and low power consumption. Its 2.8 MHz gain-bandwidth product is suitable for general-purpose closed-loop signal paths rather than high-frequency precision instrumentation. The typical operating current of 230 uA supports battery-operated equipment, while the offset voltage specification of less than 2 mV provides a useful indication of input-stage matching. The device also provides high open-loop gain and low-bias operation, as stated on the manufacturer product page.
The MCP602 family is available in standard PDIP, SOIC, and TSSOP packages, and the MCP602-E/ST ordering code places the dual amplifier in an 8-lead TSSOP. This surface-mount package supports compact layouts in industrial process control, low-power battery-operated devices, portable equipment, data-acquisition systems, test equipment, and low-end audio products. Dual packaging can reduce board area when a circuit requires amplification, buffering, or active filtering in more than one channel.
For portable and low-power designs, compare the MCP602's 230 uA typical operating current with the signal accuracy and bandwidth required by the application. Designers should also verify the complete operating-voltage range, electrical limits, input-bias current, noise performance, output-current capability, and temperature limits against the current manufacturer datasheet before releasing production hardware.
MCP602-E/ST drop-in alternatives should be evaluated primarily by package and pin compatibility, followed by supply voltage, gain-bandwidth product, input bias current, offset voltage, output swing, and operating current. Exact substitution is not assured when the required specifications differ, even if the amplifier functions appear similar. This page combines the verified manufacturer and distributor information with practical selection, application, and design guidance.
The resulting product record is intended to help engineers identify the correct TSSOP footprint, compare available alternatives, and develop an appropriate low-power analog signal path. Manufacturer documentation remains the controlling authority for ratings, test conditions, pin functions, package drawings, and revised production limits.

Low-Power Sensor Signal Conditioning
The MCP602-E/ST fits low-power sensor-conditioning circuits that amplify small differential signals while operating from a compact supply. Its rail-to-rail output swing allows the amplifier to use more of the available signal range, and the 230 uA typical operating current helps limit power demand in portable equipment. The 2.8 MHz gain-bandwidth product is suitable for common sensor, transducer, and instrumentation bandwidths. Designers should use it for moderate-frequency conditioning rather than demanding precision-front-end requirements. The complete operating voltage, offset, bias-current, and noise limits must be checked in the manufacturer datasheet before final bias, filtering, and calibration choices are established.

Portable Data-Acquisition Systems
The MCP602-E/ST is useful in portable data-acquisition equipment where each measured channel may require amplification or buffering and battery capacity is limited. Its dual configuration provides two amplifiers in one 8-TSSOP package, reducing component count, while the 230 uA typical operating current supports a low-power design strategy. The 2.8 MHz gain-bandwidth product covers many sensor-bandwidth requirements, and rail-to-rail output swing can improve use of a restricted supply range. For multiplexed or higher-impedance nodes, engineers must verify input bias current and capacitance effects in the current datasheet, then apply suitable anti-aliasing filtering.

Industrial Process-Control Inputs
The MCP602-E/ST can be used in industrial process-control input conditioning when the signal bandwidth is within the amplifier's 2.8 MHz gain-bandwidth product and the circuit operates from a compatible low-voltage supply. Its rail-to-rail output helps interface with downstream circuitry when supply headroom is constrained, while the dual package can handle two related signal paths on one board. The manufacturer specifically identifies industrial process control as a target application. Before deployment, verify the exact supply range, temperature grade, electrical limits, and transient environment for the installed equipment, and confirm whether the precision and noise required by the controlled process exceed the MCP602's verified specifications.

Low-End Audio Preamplification
The MCP602-E/ST is appropriate for low-end audio preamplification where low power and rail-to-rail output operation are more important than studio-grade noise performance. The dual 8-TSSOP package allows one amplifier to serve a channel and the other to provide buffering or gain, while its 2.8 MHz gain-bandwidth product covers the audio band. The manufacturer lists low-end audio among the intended applications. Engineers should calculate the required closed-loop gain, check output swing, and verify noise and distortion against the manufacturer test data. A conventional audio amplifier such as the NE5534 may be preferable when lower noise is required, but it must also satisfy the circuit's supply and package requirements.

Battery-Operated Monitoring Equipment
The MCP602-E/ST is suited to battery-operated monitoring equipment that performs modest amplification close to the sensor or communications circuitry. Its verified 230 uA typical operating current can contribute to a low quiescent-power budget, and the rail-to-rail output can help preserve signal headroom as the battery voltage falls. The 2.8 MHz bandwidth is more than adequate for many slow monitoring signals. Actual energy consumption must be calculated using the complete system load, regulator efficiency, and operating mode because the amplifier figure alone does not determine battery life. For medical, diagnostic, or safety-critical monitoring, review the complete accuracy, drift, and qualification requirements rather than assuming the generic amplifier is sufficient.
추천
Test and Measurement Buffering
The MCP602-E/ST can buffer low-bandwidth test and measurement signals when the instrument requires a compact, low-power dual amplifier. Its 2.8 MHz gain-bandwidth product supports higher-frequency small-signal measurements than a very-low-bandwidth precision amplifier, and the dual 8-TSSOP package can implement source-following or gain stages economically. The rail-to-rail output swing is useful when test-point voltages occupy much of the available range. Designers should verify input capacitance, bias current, output drive, settling behavior, and noise from the datasheet for the chosen gain and frequency. Precision instruments with demanding accuracy or drive requirements may need a more specialized amplifier.

설계 노트
The manufacturer's verified typical operating current is 230 uA, but system-level power also depends on the load and supply voltage. Confirm the maximum supply rating, quiescent-current test conditions, and output-current capability in the current datasheet. If the MCP602-E/ST operates from a battery rail, calculate P approximately as VDD times total current and include regulator quiescent current and downstream standby leakage. Do not extrapolate the 230 uA typical figure to guarantee a particular battery runtime.
Use the manufacturer package drawing and recommended land pattern for the 8-lead TSSOP rather than deriving dimensions from the distributor's 4.40 mm width notation. Place the required bypass capacitor adjacent to the supply and ground pins, keep the ground return path short, and provide adequate copper for thermal dissipation. Confirm pin 1 orientation against the package marking and schematic before fabrication because reversing the TSSOP can connect the positive supply to an amplifier output.
For high-impedance sources, verify input bias current, capacitance, and noise behavior from the manufacturer datasheet before selecting feedback resistors or filter values. Keep input traces short, use a continuous ground reference, and avoid routing the outputs and inputs beneath or beside switching-supply paths. Although the verified gain-bandwidth product is 2.8 MHz, closed-loop bandwidth also depends on gain and load, and stable operation must be confirmed for the selected noise-gain network.
Do not assume that every dual amplifier in a similar package is an automatic substitute. Confirm that both amplifier channels have matching supply pins, that NC or unused pins are treated correctly, and that the output swing, input common-mode range, offset, bias current, and maximum supply meet the circuit requirements. The MCP602-E/ST and MCP602T-E/ST both appear as 8-TSSOP devices in the supplied results, but their ordering-code and grade differences are not defined there.
