Applications
MCP6071T-E/OT is used in precision sensor signal conditioning, pH electrode amplifiers, and transimpedance amplifier circuits where ultra-low input bias current is critical to avoid loading high-impedance signal sources. Its rail-to-rail output swing maximizes usable signal range in 3.3 V or 5 V single-supply systems used in medical devices, portable data loggers, and industrial sensing equipment. The compact SOT-23-5 package allows integration into space-constrained analog front-end modules alongside ADCs and filters.

Frequently Asked Questions
Why is MCP6071T-E/OT preferred over standard op-amps when amplifying high-impedance sensors such as pH electrodes?
MCP6071T-E/OT has an exceptionally low input bias current of 0.0001 µA at 25°C, which means it draws almost no current from high-impedance sources like pH electrodes or photodiodes. A standard op-amp with 100 nA bias current would cause a significant voltage error across a 10 MΩ source impedance, while this device's femtoampere-range bias keeps the error negligible.
What is the gain-bandwidth product of MCP6071T-E/OT, and is it suitable for audio-frequency amplifier stages?
MCP6071T-E/OT has a gain-bandwidth product of 1.2 MHz. At unity gain it can pass signals up to approximately 1.2 MHz, and at a gain of 10 it is usable up to about 120 kHz. This makes it well-suited for audio preamplifier stages (20 Hz to 20 kHz) and low-frequency sensor conditioning where bandwidth exceeding a few hundred kHz is not needed.
How does the 74 dB minimum CMRR of MCP6071T-E/OT benefit designs in electrically noisy industrial environments?
A CMRR of 74 dB minimum (91 dB typical) means common-mode interference appearing on both input pins is rejected by a factor of more than 5000:1 relative to the differential signal. In industrial environments with 50 Hz or 60 Hz mains interference, this high CMRR prevents supply noise and ground loops from corrupting sensor readings on the 5 SOT-23-5 pins.
What is the lead time for MCP6071T-E/OT, and should engineers account for tape-and-reel availability in production planning?
MCP6071T-E/OT has a factory lead time of approximately 13 weeks from Microchip, which is longer than typical for op-amps and warrants advance ordering for production builds. The T suffix in the MPN indicates tape-and-reel packaging, confirming it is available for automated SMT assembly. Engineering teams should place orders 13 weeks ahead of production start to avoid line stoppages.
