What are the key features of MCP6021T-E/OT?

Rail-to-rail input and output swing on a single 2.5 V to 5.5 V supply for maximum dynamic range in low-voltage sensor signal conditioning
10 MHz gain-bandwidth product with 7 V/µs slew rate enabling active filter and signal amplification up to several MHz in audio and sensor applications
Ultra-low 5 pA input bias current and 90 dB CMRR minimizing error in high-impedance bridge and photodiode transimpedance amplifier circuits

What is MCP6021T-E/OT used for?

The MCP6021 is suited for single-supply sensor signal conditioning including photodiode transimpedance amplifiers, Wheatstone bridge amplifiers, and active low-pass filter stages in portable medical instruments and industrial 4 to 20 mA transmitters. Its rail-to-rail output extends usable signal swing to within millivolts of the supply rails, maximizing ADC input utilization in 3.3 V and 5 V systems. The compact SOT-23-5 package is preferred in space-constrained wearable sensor designs and battery-powered data loggers where PCB area is limited.

Frequently Asked Questions

What gain-bandwidth product does the MCP6021 provide, and which filter designs does it suit?

The MCP6021 specifies a 10 MHz gain-bandwidth product with a 7 V/µs slew rate, enabling stable operation in active Sallen-Key or multiple feedback low-pass filters with cutoff frequencies up to 100 kHz at gains of 10 V/V, which covers audio anti-aliasing filters and sensor signal conditioning in industrial data acquisition front-ends.

How low is the input bias current of the MCP6021T-E/OT, and why does it matter for photodiode circuits?

The MCP6021 has a maximum input bias current of 5 pA, low enough to drive transimpedance amplifier designs with feedback resistors above 10 MΩ without introducing significant offset voltage errors, enabling picoampere-level photodiode current measurement in optical sensors and fluorescence detection instruments operating on a single 5 V supply.

What supply voltage range does the MCP6021 support, and how does this affect portable design flexibility?

The MCP6021 operates from a single supply of 2.5 V to 5.5 V or a split supply of ±1.25 V to ±2.75 V, covering 3.3 V LDO-regulated systems and 5 V industrial supplies alike. This flexibility allows the same PCB to operate from a LiPo battery at 3.7 V or a regulated bench supply at 5 V without component changes.

For a compact 4-20 mA industrial transmitter, what advantage does the MCP6021 SOT-23-5 package offer?

The MCP6021T-E/OT SOT-23-5 package occupies roughly 3 mm x 1.75 mm of PCB area with a 0.95 mm pin pitch, allowing placement within 2 mm of the signal conditioning network adjacent to pressure sensor bridges on transmitter PCBs smaller than 20 mm x 20 mm, reducing parasitic trace impedance and improving signal integrity at 4-20 mA output bandwidths.

How does the MCP6021 CMRR of 90 dB benefit Wheatstone bridge measurement accuracy?

With a 90 dB common-mode rejection ratio, the MCP6021 attenuates common-mode supply and ground noise by a factor of over 30000:1, meaning a 1 mV common-mode noise on a 5 V bridge excitation rail contributes less than 0.03 µV referred-to-input error, preserving measurement resolution better than 16 bits for load cell and strain gauge applications.
