Key Features

  • 60 MHz gain-bandwidth product enables high-speed signal amplification in compact designs
  • 66 dB minimum common-mode rejection ratio for accurate differential signal processing
  • 5-pin SOT-23 package minimises PCB footprint in space-constrained portable equipment
  • 5 nA maximum bias current preserves accuracy in high-impedance sensor front-ends

Applications

The MCP661T-E/OTVAO suits active filter stages, ADC input buffers, and transimpedance amplifiers in industrial and portable medical instruments requiring 60 MHz bandwidth from a small 5-pin SOT-23 package. Its low 5 nA bias current makes it ideal for high-impedance photodiode and sensor amplification circuits. Communications equipment and test instrumentation that demand wide bandwidth with minimal board space also benefit from this device.

Frequently Asked Questions

What gain-bandwidth product does the MCP661T-E/OTVAO provide and how does it affect filter design?

The MCP661T-E/OTVAO delivers a 60 MHz gain-bandwidth product, allowing designers to implement active low-pass filters with cutoff frequencies in the low MHz range at gains of 10 or more. This bandwidth is sufficient for anti-aliasing filters ahead of 12-bit or 14-bit ADCs sampling at several megasamples per second, all within a compact 5-pin SOT-23 package.

How suitable is the MCP661T-E/OTVAO for photodiode transimpedance amplifier circuits with high source impedance?

With a maximum bias current of only 5 nA, the MCP661T-E/OTVAO is well suited for transimpedance amplifier designs where photodiode source impedance exceeds 1 MΩ. The low bias current minimises the voltage error introduced at the summing node, and the 66 dB common-mode rejection ratio helps suppress noise on the 5 V supply rail.

When would a designer choose the MCP661T-E/OTVAO over a lower-bandwidth op-amp for a 5 V portable instrument?

A designer targeting portable data-acquisition instruments that require sampling rates above 1 MSPS would select the MCP661T-E/OTVAO because its 60 MHz bandwidth prevents signal roll-off at the ADC front end. The 5-pin SOT-23 package occupies less than 3 mm² of board space, making it practical in battery-powered handheld instruments where board area and supply current are both tightly constrained.
