What are the key features of MCP6294-E/ST?
- Quad op-amp with 10 MHz gain-bandwidth product and rail-to-rail output swing, enabling four independent active filter or amplifier stages in a single TSSOP-14 package
- Ultra-low 5 nA maximum input bias current and 80 dB CMRR for precision multi-channel sensor signal conditioning from 1.8 V to 6 V supplies
- 1-week factory lead time availability in compact TSSOP-14 footprint, reducing BOM risk for high-volume portable instrumentation and audio designs
What is MCP6294-E/ST used for?
The MCP6294-E/ST is designed for multi-channel active filter banks, quad-channel ADC driver circuits, and portable instrumentation front-ends where four amplifier stages must fit within minimal PCB area. Its 10 MHz bandwidth supports audio-band and sensor-conditioning filters with corner frequencies up to several hundred kilohertz. The 1.8 V minimum supply enables direct operation from single-cell Li-ion batteries in wearable and handheld measurement devices.

Frequently Asked Questions
What gain-bandwidth product does the MCP6294-E/ST provide and at what closed-loop gain does it achieve 1 MHz signal bandwidth?
The MCP6294-E/ST has a 10 MHz gain-bandwidth product, meaning at a closed-loop gain of 10 V/V the -3 dB bandwidth is approximately 1 MHz. This makes it suitable for audio anti-aliasing filters, sensor signal conditioning up to 500 kHz, and ADC driver stages requiring flat response across the full audio band.
How does integrating four op-amps in the MCP6294-E/ST reduce PCB area compared to using discrete single-channel parts?
The TSSOP-14 package of the MCP6294-E/ST measures approximately 5 mm × 4.4 mm and houses 4 amplifiers, compared to four individual SOT-23-5 packages occupying roughly 4 × 4.6 mm² each. Using the quad device reduces footprint by about 70% and cuts the number of passive decoupling capacitors needed from four to two shared supply pins.
For a 4-channel ECG front-end, why is the 5 nA input bias current of the MCP6294-E/ST important?
ECG electrodes present source impedances of 10 kΩ to 100 kΩ. A 5 nA bias current through 100 kΩ generates only 0.5 µV of offset error, well below the 10 µV baseline noise floor of typical ECG measurements. This ensures that the MCP6294-E/ST does not add clinically significant bias to biopotential signals across all 4 channels simultaneously.
Which supply configurations support the MCP6294-E/ST in mixed 3.3 V and 5 V system designs?
The MCP6294-E/ST operates from 1.8 V to 6 V single supply, making it directly compatible with 3.3 V system rails, 5 V legacy analog rails, and split ±2.5 V supplies. The rail-to-rail output ensures the full supply swing is available to downstream ADCs, simplifying level shifting in mixed-voltage signal chains where analog headroom is limited.
