What are the key features of MCP625-E/UN?
- Dual op-amp with 20 MHz gain-bandwidth product and auto-zero calibration delivering sub-µV effective offset voltage in precision signal chains
- 68 dB minimum / 84 dB typical CMRR with rail-to-rail output for maximum dynamic range in single-supply 2.4 V to 5.5 V systems
- 5 nA maximum input bias current in a compact MSOP-10 package, ideal for high-impedance sensor interfaces with minimal loading error
What is MCP625-E/UN used for?
The MCP625-E/UN is suited for precision instrumentation amplifier front ends, bridge sensor signal conditioning, and electrochemical sensor interfaces where auto-zero correction eliminates DC offset drift without external trimming. Its 20 MHz bandwidth supports audio and mid-frequency industrial sensing applications operating up to a few megahertz. The dual-channel MSOP-10 package saves board space in handheld measurement instruments, medical analyzers, and industrial transmitters requiring two precision amplification channels.

Frequently Asked Questions
How does auto-zero calibration in MCP625-E/UN improve DC accuracy compared to standard op-amps?
The MCP625-E/UN uses an internal auto-zero sampling cycle to continuously measure and correct its own input offset voltage, achieving an effective offset below 10 µV versus a typical 1 mV to 5 mV offset in standard op-amps. This internal correction also cancels offset drift with temperature, keeping offset below 10 µV/°C across the -40°C to +125°C operating range, which is critical in bridge sensors and 4-20 mA transmitters where DC accuracy directly translates to measurement error.
At a closed-loop gain of 100, what signal bandwidth does MCP625-E/UN deliver?
With a 20 MHz gain-bandwidth product, the MCP625-E/UN achieves a -3 dB bandwidth of approximately 200 kHz at a closed-loop gain of 100 V/V. This is sufficient for industrial vibration sensors, electrochemical detection circuits, and strain-gauge amplifiers operating up to 100 kHz. For comparison, a 1 MHz GBW op-amp such as MCP6001 would be limited to only 10 kHz at the same gain, making MCP625 significantly more capable for mid-frequency precision applications.
What input bias current does MCP625-E/UN draw and why does it matter for high-impedance pH sensors?
The MCP625-E/UN specifies a maximum input bias current of 5 nA (0.005 µA), which produces only 5 mV of voltage error across a 1 MΩ source impedance. This is critical for pH electrode interfaces where the glass membrane resistance can exceed 100 MΩ; at 5 nA bias, the additional measurement error is only 0.5 mV per 100 MΩ, well within the 1 mV resolution required for 0.01 pH unit accuracy. Higher-bias amplifiers (µA range) would introduce millivolts of error that corrupt pH readings.
How does the MCP625-E/UN dual-channel package compare to using two single MCP621 op-amps for a differential instrumentation stage?
Two MCP621 single op-amps in SOT-23-5 occupy approximately 2 x 10 mm2 versus MCP625-E/UN's single MSOP-10 footprint at about 9 mm2, saving roughly 50% board area in a 2-channel design. More importantly, matched auto-zero characteristics within the dual package ensure that both channels share similar offset and drift behavior, improving the common-mode rejection of a 2-op-amp instrumentation amplifier configuration to greater than 80 dB. Using two separate SOT-23 devices from different production lots may introduce offset mismatches exceeding 500 µV.
