MCP606-I/SN - 155kHz Micropower CMOS Op Amp | Microchip
Teilenummer: MCP606-I/SN ✓ AktivMCP606-I/SN Übersicht
An operational amplifier, or op amp, is a high-gain differential amplifier that compares two input voltages and drives its output according to their difference. Widely used as a building block in analog signal chains, the MCP606 belongs to the broader hierarchy of operational amplifier, analog amplifier, analog signal-conditioning IC, and semiconductor. Its micropower bias and broad supply range make it useful in battery-powered instrumentation, sensor interfaces, and portable measurement systems.
Key specifications include a 2.5 V to 6.0 V single-supply operating range, unity-gain stability, 80 pA maximum input bias current at +85 °C, and 25 µA maximum quiescent current. The 155 kHz gain-bandwidth product supports moderate-bandwidth amplification, while the 0.08 V/µs slew rate provides adequate response for slow sensor, filtering, and general-purpose analog signals. Rail-to-rail output swing improves usable output range on low-voltage supplies.
The MCP606 uses advanced CMOS technology to achieve low bias current, high open-loop gain, and low power consumption. Its unity-gain-stable architecture allows operation as a voltage follower without external compensation. The input offset voltage is specified at no more than 250 µV, making it appropriate for signal paths where offset must remain controlled relative to small sensor outputs. Common-mode rejection is identified by Microchip as a key family-level performance characteristic for precision interface circuits.
Typical applications include low-power sensor amplification, portable medical monitoring, battery-powered data acquisition, audio and communication signal conditioning, industrial process measurement, and general voltage buffering. The device is especially useful where a 2.5 V minimum supply operation, low quiescent current, and rail-to-rail output are more important than the bandwidth or slew rate of a high-speed amplifier.
When designing around the MCP606, check input and output common-mode limits over the complete supply range and account for the 250 µV maximum offset when resolving small signals. Place input and output bypass capacitors close to the device, use a stable feedback network for closed-loop gain, and avoid configurations that exceed the amplifier's 155 kHz gain-bandwidth product or 0.08 V/µs slew-rate capability.

Typische Anwendungen
MCP606-I/SN ist geeignet für 6 Anwendungs: Battery-Powered Sensor Conditioning, Portable Medical Monitoring, Industrial Process Measurement, Low-Power Data Acquisition, Audio and Communication Buffering, General Voltage Buffering.
Battery-Powered Sensor Conditioning
The MCP606-I/SN fits battery-powered sensor conditioning because it operates from 2.5 V to 6.0 V and has 18.7 µA typical operating current. Its 80 pA maximum input bias current at +85 °C limits loading on high-impedance sensing elements, while the 250 µV maximum offset remains manageable for signals well above the microvolt scale. Place the amplifier directly at the sensor to minimize trace resistance and interference, then use stable feedback components selected for the intended gain. The 155 kHz gain-bandwidth product supports low-bandwidth measurements without introducing the power and speed of a larger general-purpose amplifier.
Empfohlen
Portable Medical Monitoring
The MCP606-I/SN is suitable for low-level physiological signal conditioning in portable monitoring equipment when its 250 µV maximum offset and 80 pA maximum input bias current are acceptable for the selected signal. The 18.7 µA typical operating current supports constrained power budgets, and the 2.5 V minimum supply fits compact battery-powered designs. Its unity-gain stability permits straightforward voltage-following stages around sensor front ends. Designers should still evaluate input common-mode range, noise performance, patient-safety isolation requirements, and the noise and accuracy of the connected sensor rather than treating signal amplification as a complete medical-safety solution.
Empfohlen
Industrial Process Measurement
The MCP606-I/SN can amplify low-level process signals in industrial measurement systems that operate from a 2.5 V to 6.0 V control rail. Its low input bias current is valuable when the transducer has high source impedance, while the 250 µV maximum offset helps preserve small measurement signals. The amplifier provides rail-to-rail output swing for better utilization of low-voltage supply ranges and remains unity-gain stable for buffer stages. In deployed equipment, protect the input path from transients, keep sensitive feedback nodes compact, and confirm that the 155 kHz bandwidth and 0.08 V/µs slew rate cover the required control-loop or sensor bandwidth.
Empfohlen
Low-Power Data Acquisition
The MCP606-I/SN serves as an input amplifier or buffer in a low-power data-acquisition chain where the source signal changes slowly relative to its 155 kHz gain-bandwidth product. Its 18.7 µA typical operating current limits amplifier overhead in battery-powered loggers, and the 80 pA maximum input bias current reduces errors from high-impedance sensor networks. Unity-gain stability also supports voltage-following configurations without an added compensation network. Select resistor values to control thermal noise and offset contribution, confirm that the input signal remains inside the common-mode range, and account for ADC acquisition requirements when defining the amplifier bandwidth.
Empfohlen
Audio and Communication Buffering
The MCP606-I/SN can serve as a low-level buffer or gain stage in audio and communication interfaces whose bandwidth and amplitude remain within the device's 155 kHz gain-bandwidth product and 0.08 V/µs slew rate. Rail-to-rail output swing improves headroom in 2.5 V to 6.0 V systems, while low bias current avoids significant loading on sensitive upstream circuitry. Its 250 µV maximum offset is generally suitable for signal paths well above the microvolt level. For audio applications, evaluate noise density and distortion against the required signal-to-noise ratio; for communication interfaces, verify bandwidth, settling behavior, and output-drive requirements before finalizing the gain configuration.
Empfohlen
General Voltage Buffering
The MCP606-I/SN is a practical choice for general voltage buffering because it is unity-gain stable, provides rail-to-rail output swing, and draws 18.7 µA typical operating current. These properties allow a high-impedance source to drive a following stage without demanding a high-speed amplifier. The 250 µV maximum input offset voltage should be included in the error budget, while the 80 pA maximum input bias current helps when source resistance is high. Keep the op-amp input and feedback tracks short, place the bypass capacitor at the supply pin, and verify output loading because rail-to-rail output does not guarantee unlimited drive current into every downstream load.

Wichtigste Unterscheidungsmerkmale
- Combines moderate bandwidth with micropower operation (vs. MCP606T-I/SN)
- Supports direct voltage-following configurations (vs. MCP606T-I/SN)
- Limits loading of high-impedance sensors (vs. MCP606T-I/SN)
Designhinweise
Decouple the 2.5 V to 6.0 V supply close to the MCP606-I/SN with the capacitance recommended by the manufacturer application guidance. Keep the power-loop return path short and separate from sensitive input and feedback routing. The amplifier's typical operating current is 18.7 µA, but total supply demand also includes input bias current, feedback-network current, and output loading. Confirm capacitor voltage rating, DC-bias derating, and startup behavior before power-sequencing the analog rail.
Route the non-inverting input and inverting feedback node as short as practical because parasitic capacitance and leakage can alter gain and stability. Connect the bypass capacitor directly to the supply and ground pins rather than routing through the general signal ground plane. For voltage followers, keep the output and feedback connection compact and verify the load current independently; rail-to-rail output swing does not establish the available drive current at every output voltage.
Do not treat the 155 kHz gain-bandwidth product as unlimited small-signal bandwidth at every gain. Closed-loop bandwidth, slew rate, output loading, and loop gain jointly determine response. Include the 250 µV maximum input offset voltage in the error budget for low-level signals, verify input common-mode limits across the 2.5 V to 6.0 V supply range, and avoid operating the output outside its specified swing despite the rail-to-rail-output feature.
