What are the key features of MCP601RT-E/OT?
- Rail-to-rail output swing enabling full-scale signal swing down to within millivolts of both supply rails in low-voltage systems
- 2.8 MHz gain-bandwidth product with 2.3 V/µs slew rate for audio and sensor signal conditioning
- Ultra-low 0.005 µA input bias current minimizing offset errors in high-impedance sensor interfaces
- Single-supply operation from 2.7 V to 6 V in a 5-pin SOT-23 package for compact portable designs
What is MCP601RT-E/OT used for?
The MCP601RT-E/OT is used in battery-powered sensor interfaces, active filters, and signal conditioning circuits where a single-supply rail-to-rail output op-amp must operate correctly down to 2.7 V. Its low 0.005 µA bias current makes it ideal for high-impedance photodiode transimpedance amplifiers and pH electrode buffers in handheld instrumentation. The 2.8 MHz GBW and SOT-23-5 footprint also suit audio preamplifier stages and ADC driver circuits in space-constrained consumer and medical devices.

Frequently Asked Questions
What gain-bandwidth product and slew rate does MCP601RT-E/OT offer, and is it fast enough for 100 kHz active filter stages?
The MCP601RT-E/OT has a 2.8 MHz gain-bandwidth product and 2.3 V/µs slew rate. At unity gain it maintains flat response to about 2.8 MHz; in a Sallen-Key low-pass filter configured for 100 kHz cutoff with a gain of 2, the effective bandwidth is 1.4 MHz — more than a decade above the pole frequency, so phase error and gain error at 100 kHz remain well within 0.5 dB.
How does MCP601RT-E/OT perform as a photodiode transimpedance amplifier in a 3.3 V system?
With a 0.005 µA maximum input bias current, the MCP601RT-E/OT introduces less than 5 mV of offset across a 1 MΩ transimpedance feedback resistor, making it suitable for photodiode currents as low as 10 nA. The rail-to-rail output on a 3.3 V single supply allows the amplifier to swing from near 0 V to approximately 3.29 V, maximizing dynamic range in optical sensor and barcode reader designs.
Can MCP601RT-E/OT operate from a single 3 V lithium cell without a negative rail?
Yes. The MCP601RT-E/OT is specified for single-supply operation from 2.7 V to 6 V, so a 3 V CR2032 lithium cell is within its operating range. The rail-to-rail output stage ensures the output can swing to within approximately 25 mV of ground and within 25 mV of the 3 V supply, preserving usable output dynamic range even at the minimum supply voltage.
What are the CMRR and offset voltage specs of MCP601RT-E/OT, and how do they compare for precision difference amplifier circuits?
The MCP601RT-E/OT specifies a minimum CMRR of 75 dB and a typical CMRR of 90 dB, with a typical input offset voltage of 0.25 mV (1.5 mV maximum at 25°C). For a difference amplifier with 1% resistor matching, the resistor mismatch limits CMRR to about 46 dB, so the op-amp's 75 dB minimum does not degrade system-level CMRR, making it adequate for industrial sensor bridge measurements with moderate precision requirements.
