What are the key features of MCP6L71T-E/OT?
- 2 MHz gain-bandwidth product with internal frequency compensation enables stable closed-loop operation without external capacitors
- 91 dB typical CMRR provides strong rejection of common-mode interference in differential sensor signal chains
- SOT-23-5 package with extended temperature range (-40°C to +125°C) fits space-constrained industrial and portable designs
What is MCP6L71T-E/OT used for?
The MCP6L71T-E/OT is suited for general-purpose signal conditioning, active low-pass filtering, and buffer stages in industrial sensors, portable medical instruments, and consumer electronics operating across the -40°C to +125°C extended temperature range. Its 2 MHz bandwidth and low-profile SOT-23-5 package make it an efficient choice for single-channel amplifier stages in applications where board area is limited and moderate bandwidth is sufficient.

Frequently Asked Questions
For a 10 kHz active low-pass filter using MCP6L71T-E/OT, how much gain-bandwidth margin does the 2 MHz GBW product allow?
At a 10 kHz signal frequency with unity-gain configuration, the MCP6L71T-E/OT's 2 MHz gain-bandwidth product provides 200x bandwidth headroom, which is more than sufficient for a second-order Sallen-Key or multiple feedback filter with gains up to 10 V/V (20 dB). For a gain of 10 V/V, closed-loop bandwidth is approximately 200 kHz, giving 20x margin above the 10 kHz passband edge with minimal phase error.
How does the 91 dB CMRR of MCP6L71T-E/OT help in rejecting 50 Hz or 60 Hz power-line interference in sensor circuits?
With 91 dB typical CMRR, the MCP6L71T-E/OT attenuates common-mode 50 Hz or 60 Hz noise by a factor of approximately 35,000:1, reducing a 1 V power-line coupled signal to below 30 µV at the differential output. This rejection level is sufficient for most resistive bridge sensor interfaces where power-line interference appears as a common-mode signal across the bridge output, provided the source impedance imbalance stays below a few hundred ohms.
What supply voltage range does MCP6L71T-E/OT support, and how does it perform from a 3.3 V single supply?
The MCP6L71T-E/OT operates from a single supply of 1.8 V to 6 V or a dual supply of ±0.9 V to ±3 V. At 3.3 V single-supply, the rail-to-rail input and output stages allow the common-mode input range to include both supply rails, and the output can swing to within approximately 50 mV of ground and VCC at light loads, maximizing dynamic range in 3.3 V ADC-interfaced sensor conditioning circuits.
How does the extended temperature rating of MCP6L71T-E/OT benefit industrial sensor deployments compared to commercial-grade op-amps?
The -E suffix on MCP6L71T-E/OT denotes extended temperature rating from -40°C to +125°C, versus the 0°C to +70°C commercial range. Industrial sensor nodes mounted near heat sources, outdoor enclosures, or automotive-adjacent environments can experience junction temperatures above 85°C under load, and the extended-rated device guarantees all key parameters including 4000 µV maximum input offset voltage and 91 dB CMRR across the full temperature span without derating.
