LMH6647MAX/NOPB

Instrumentation, Op Amps, Buffer Amps Overview

The LMH6647MAX/NOPB is a single-channel operational amplifier manufactured by Texas Instruments, utilizing BiCOM technology. It features rail-to-rail input and output capabilities with a shutdown option. Key electrical parameters include a gain-bandwidth product of 55 MHz, a slew rate of 22 V/us, and an operating supply current of approximately 650 uA to 700 uA. The device supports dual supply voltages ranging from 1.25 V to 6 V or single supplies up to 12 V. It offers a common-mode rejection ratio of 85 dB and power supply rejection of 75 dB. The input offset voltage is typically 3 mV, with an input bias current of 2 uA. It is housed in an SOIC-8 package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer designation as Texas Instruments, which acquired National Semiconductor. Confirm the suffix NOPB indicates lead-free and RoHS compliance. Ensure the package type matches the required SOIC-8 footprint for PCB layout compatibility. Check for any specific ordering prefixes that may affect availability or documentation access.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single-channel op amp with rail-to-rail I/O and shutdown functionality is required. Consider the 55 MHz bandwidth and 22 V/us slew rate for moderate-speed applications. Evaluate the 650 uA supply current against system power budgets. Compare input offset voltage and bias current specifications against other single-channel options if precision is critical.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LMH6647 family of high-speed, low-power operational amplifiers. The MAX/NOPB variant specifically denotes the SOIC-8 surface-mount package with industrial temperature range operation (-40°C to +85°C). It is distinct from dual-channel variants like the LMH6648 or smaller package versions such as the MFX/SOT-23-6.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

LMH6647MFX/NOPB: Same functional specifications but in SOT-23-6 package; requires footprint adaptation.
