What are the key features of MCP6404-E/ST?
- Quad op-amp channels in a single 14-pin TSSOP for compact multi-channel signal chains
- 1.8 V minimum supply voltage enabling single-cell or low-voltage system integration
- 1 MHz gain-bandwidth product supporting active filters up to hundreds of kHz
- Ultra-low bias current maximum of 0.0001 µA (0.1 pA) for high-impedance sensor inputs
- 78 dB typical CMRR rejecting common-mode interference in noisy environments
What is MCP6404-E/ST used for?
The MCP6404-E/ST is well suited for battery-powered instrumentation, IoT sensor nodes, and portable medical devices where four amplifier channels must operate from a single 1.8 V to 5.5 V cell with minimal quiescent current. Its ultra-low 0.1 pA bias current makes it particularly effective at the front end of high-impedance pH, electrochemical, or photodiode sensor interfaces where leakage errors must be kept below nanoampere levels.

Frequently Asked Questions
How does the 0.0001 µA maximum bias current of MCP6404-E/ST affect measurement accuracy with a high-impedance pH sensor?
A pH glass electrode typically has an output impedance of 100 MΩ to 1 GΩ. With the MCP6404's maximum bias current of 0.0001 µA (0.1 pA), the resulting offset voltage error across a 100 MΩ source impedance is only 10 µV, which is negligible compared to the 59 mV/pH Nernst response. This makes the MCP6404 far more accurate for pH measurements than general-purpose op-amps with nanoampere-range bias currents.
For a 4-channel active low-pass filter running from a 3.3 V rail, what cutoff frequency is achievable with MCP6404-E/ST?
With a 1 MHz gain-bandwidth product, a second-order Sallen-Key low-pass stage at unity gain can achieve a -3 dB frequency up to approximately 700 kHz while maintaining adequate phase margin. For typical sensor anti-aliasing needs below 10 kHz, the GBW leaves more than 100× of closed-loop bandwidth to spare, ensuring flat response, minimal phase error, and excellent stability across all 4 channels simultaneously.
Is MCP6404-E/ST a viable lower-power replacement for MCP6024 in a 3.3 V portable instrument?
Both devices share the quad op-amp format in a 14-pin TSSOP and rail-to-rail output topology, with MCP6404 targeting lower supply voltages down to 1.8 V compared to MCP6024's 2.7 V minimum. If the application operates from a 3.3 V rail and requires the same 1 MHz bandwidth, MCP6404 is a direct functional substitute with the benefit of extended low-voltage compatibility, making it the preferred choice when the supply may sag below 2.7 V under battery discharge.
