MCP6002T-I/SN: A Comprehensive Look at the Low-Power Dual-Channel Rail-to-Rail Operational Amplifier
5/21/2026 3:04:01 AM
The MCP6002T-I/SN is a dual-channel, low-power, general-purpose CMOS operational amplifier introduced by Microchip Technology. Housed in an 8-pin SOIC package, the device delivers rail-to-rail input and output capability across a single-supply voltage range of 1.8 V to 6 V, making it an ideal choice for signal conditioning in battery-powered equipment and portable electronics. Its typical gain-bandwidth product is 1 MHz, while the quiescent current is just 100 μA per amplifier, striking an excellent balance between performance and power consumption.

Product Naming and Design Features
In the device's part-numbering convention, the suffix "T" indicates tape-and-reel packaging, while the absence of "T" denotes tube packaging; the actual silicon die is identical in both cases. The rail-to-rail input/output design enables the amplifier to maintain linear amplification over the entire supply-voltage range. Combined with an ultra-low input bias current of only 1 pA, this makes the device exceptionally well suited for use with high-impedance signal sources such as photodiodes and piezoelectric sensors.
Typical Application Scenarios
Leveraging these technical characteristics, the device can be deployed across a wide variety of analog signal-processing scenarios: as a front-end preamplifier for sensor signals in portable medical equipment; for high-precision amplification of weak photocurrents in photodetection circuits; for constructing low-pass, high-pass, or band-pass filter circuits in analog filter design; for providing low-power signal conditioning in battery-powered IoT sensor nodes; as well as in industrial control and portable instrumentation.
Frequently Asked Questions
Q: How can stable circuit operation be ensured?
A: It is recommended to place appropriate bypass capacitors near the power-supply pins to reduce power-supply noise interference and ensure stable device operation.
Q: What are the key advantages of this device?
