MCP6481T-E/LTY

Instrumentation, Op Amps, Buffer Amps Overview

The MCP6481T-E/LTY is a single-channel operational amplifier from the MCP6481/2/4 family, manufactured using advanced CMOS technology. It operates within a supply voltage range of 2.2V to 5.5V and features rail-to-rail input and output capabilities. Key electrical specifications include a typical gain bandwidth product of 4 MHz, a slew rate of 2.7 V/µs, and a maximum input offset voltage of ±1.5 mV. The device draws a typical quiescent current of 240 µA per amplifier and maintains an input bias current as low as 1 pA at +25°C. It is designed for unity-gain stability without phase reversal and supports an extended operating temperature range from -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the ordering suffix 'LTY' corresponds to the SC-70-5 package type as defined in the official Microchip datasheet DS20002322C. Confirm the 'E' designation indicates the extended temperature grade (-40°C to +125°C). Ensure compatibility with single-supply operation requirements between 2.2V and 5.5V. Cross-reference the specific tape-and-reel quantity if applicable, though packaging details should be validated against the manufacturer's current documentation.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low input bias current is critical for maintaining accuracy with high-impedance sensors. The rail-to-rail I/O allows for maximum dynamic range in low-voltage single-supply systems. Consider the 4 MHz bandwidth and 2.7 V/µs slew rate for applications requiring moderate speed. Verify PCB layout constraints regarding surface leakage currents, as guard rings may be necessary to preserve the low bias current performance specified in the datasheet.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MCP6481/2/4 family of low-power, low-input bias current operational amplifiers. The MCP6481 represents the single-channel configuration, while MCP6482 and MCP6484 offer dual and quad channels respectively. All variants share identical electrical characteristics and are fabricated on the same CMOS process node, ensuring consistent performance metrics across the family.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Microchip lists the MCP6471/2/4 (2 MHz) and MCP6491/2/4 (7.5 MHz) as related parts within the same low-input bias current portfolio. These alternatives offer different bandwidth specifications while maintaining similar low-power and low-bias current characteristics.
