Key Features
- 10 MHz gain-bandwidth product with 7 V/µs slew rate for wideband active filter and amplifier designs up to 5.5 V supply
- 5 nA maximum input bias current enabling high-impedance photodiode and electrometer-grade sensor interfacing
- Rail-to-rail input and output with 65 dB minimum CMRR in compact 8-pin SOIC for single-supply signal chains
Applications
The MCP6291-E/SN is suited for active anti-aliasing filters, transimpedance amplifiers, and wideband sensor signal chains operating from a 2.5 V to 5.5 V single supply where its 10 MHz GBW extends the usable bandwidth well beyond audio frequencies. Photodiode receivers in optical proximity sensors and smoke detectors benefit from its 5 nA maximum input bias current, which minimizes offset error when interfacing high-impedance photodetectors. It also serves as a fast comparator substitute and voltage follower in data acquisition front ends that need a low-cost 8-pin SOIC solution with rail-to-rail swing.

Frequently Asked Questions
What gain-bandwidth product and slew rate does the MCP6291-E/SN deliver for wideband amplifier stages?
The MCP6291-E/SN provides a 10 MHz gain-bandwidth product and a 7 V/µs slew rate, allowing designers to build amplifiers with closed-loop gains up to 10 V/V while maintaining a -3 dB bandwidth of 1 MHz. The 7 V/µs slew rate supports full-swing output transitions on signals up to several hundred kilohertz without slew-rate limiting in a 2.5 V to 5.5 V supply environment.
How does the 5 nA input bias current of the MCP6291-E/SN benefit high-impedance sensor interfaces?
With a maximum input bias current of only 5 nA (0.005 µA), the MCP6291-E/SN produces less than 0.5 mV of offset voltage across a 100 kΩ source impedance, which is essential for transimpedance amplifiers connected to photodiodes, pH electrodes, and other high-impedance sensors where even microamp-level bias currents would create unacceptable DC errors.
What CMRR specification does the MCP6291-E/SN meet, and how does it compare to budget single-supply op-amps?
The MCP6291-E/SN guarantees a minimum CMRR of 65 dB and typically achieves 80 dB, rejecting common-mode interference on both inputs by a factor of over 3000 at DC. Many budget single-supply op-amps specify only 55-60 dB minimum CMRR, making the MCP6291-E/SN a stronger choice for differential measurement in noisy industrial environments where 50 Hz or 60 Hz mains coupling on sensor cables would degrade accuracy.
When is MCP6291-E/SN a better fit than MCP6004-I/ST for a single-channel filter design?
When the design requires a single amplifier channel with 10 MHz GBW rather than four channels at 1 MHz GBW, the MCP6291-E/SN in an 8-pin SOIC is more appropriate than the quad MCP6004-I/ST. The MCP6291's higher 7 V/µs slew rate also supports fast signal edges in pulse-shaping circuits and active high-pass filters above 100 kHz, where the MCP6004's lower bandwidth would introduce significant gain roll-off.
