LMH6618MKE/NOPB

Overview

The LMH6618MKE/NOPB is a single-channel, voltage-feedback operational amplifier manufactured by Texas Instruments. It features rail-to-rail input and output capabilities with a gain-bandwidth product of 71 MHz and a slew rate of 57 V/µs. The device operates on a single supply voltage ranging from 2.7 V to 11 V, consuming 1.25 mA of quiescent current per channel while delivering up to 35 mA of output current. Key electrical specifications include an input offset voltage of 1.3 mV, input bias current of 1.9 µA, common-mode rejection ratio of 108 dB, and input voltage noise density of 10 nV/√Hz. It is housed in a compact SOT-23-6 package and supports a wide operating temperature range from -40°C to +125°C.

Procurement Notes

Verify the complete part number including the suffix /NOPB to ensure compliance with RoHS standards and lead-free manufacturing requirements. Confirm that the SOT-23-6 thin package matches your PCB footprint design. Check the datasheet for specific thermal dissipation limits under high load conditions. Ensure the supply voltage does not exceed the maximum rating of 11 V to prevent device damage. Validate the operating temperature range against your environmental specifications.

Selection Notes

Select this component when a single-channel op amp with rail-to-rail I/O is required in a small form factor. It is suitable for designs needing moderate bandwidth and low power consumption. Consider the 1.25 mA quiescent current for battery life calculations. Compare the 71 MHz gain-bandwidth product against system frequency requirements. Evaluate the 35 mA output drive capability against load impedance needs.
