LMH6647MAX/NOPB

Instrumentation, Op Amps, Buffer Amps Overview

The LMH6647MAX/NOPB is a single-channel operational amplifier manufactured by Texas Instruments, housed in an SOIC-8 surface-mount package. It operates on a supply voltage range of 2.5 V to 12 V with a typical operating supply current of 700 µA. The device features a gain-bandwidth product of 55 MHz and a slew rate of 22 V/µs. Key electrical specifications include a maximum input offset voltage of 3 mV, an input bias current of 2 µA, and a common-mode rejection ratio of 85 dB. It provides a per-channel output current of 20 mA and supports rail-to-rail input and output capabilities.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'MAX' corresponds to the SOIC-8 package and 'NOPB' indicates lead-free/RoHS compliance when sourcing. Confirm that the datasheet specifies the exact operating temperature range of -40°C to +85°C for this variant. Ensure the component matches the single-channel configuration required for the design.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring low power consumption alongside moderate bandwidth. The rail-to-rail I/O capability makes it suitable for single-supply systems where maximizing dynamic range is critical. Consider the 20 mA output drive capability for driving moderate loads without external amplification stages.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LMH6647 family of high-speed, low-power operational amplifiers from Texas Instruments. The family includes variants with different package options such as SOT-23-6 (LMH6647MFX) and MSOP (LMH6643). The MAX/NOPB designation specifically identifies the industrial temperature grade version in the standard SOIC-8 footprint.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible alternatives within the same family include LMH6647MFX/NOPB for SOT-23-6 packaging or LMH6647MA for non-NOPB versions. Cross-family replacements require verification of GBW, slew rate, and supply voltage compatibility.
