The Microchip MCP6034-E/SL is a quad general-purpose operational amplifier designed for ultra-low-power applications. Each of its four channels draws just a fraction of the total 900 nA supply current, making it a strong candidate for battery-powered instrumentation, portable medical devices, and always-on sensor interfaces where every microamp counts. The 10 kHz gain-bandwidth product and 0.004 V/µs slew rate tell you this is not a fast amplifier — it is sized for DC and low-frequency signals: temperature monitoring, strain-gauge conditioning, and threshold detection loops.
Temperature range and industrial fit
The -E/ suffix in the order code flags the extended temperature grade — if your BOM calls for the commercial-range variant, the part number will differ.
Package and mounting
For a micropower op-amp, those numbers are tight enough that you will not need to trim the offset in most low-gain DC paths. The 1 pA bias means you can use high-value feedback resistors (into the megohm range) without introducing a significant voltage error — useful for transimpedance amplifiers on photodiode signals where you are trying to keep the noise floor down.
Output drive and package reality
Each channel can source or sink 23 mA, which is enough to drive a logic input, a small LED indicator, or the reference pin of an ADC. The package ships in Tube form — if your pick-and-place line expects Tape & Reel, check the reeled variant (MCP6034T-E/SL). The 14-SOIC body is 3.90 mm wide, a common footprint that matches many second-source quad op-amps.
