Overview
The LMH6551MMX is a high-speed, single-channel voltage feedback operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 370 MHz and a slew rate of 2.4 kV/µs. The device operates on a supply voltage range of 3 V to 12 V with a typical operating current of 11.5 mA per channel. Key electrical specifications include an input offset voltage of 4 mV, input bias current of 4 µA, common-mode rejection ratio of 78 dB, and input voltage noise density of 6 nV/√Hz. It provides an output current capability of 60 mA per channel and is housed in an 8-pin VSSOP package.
Feature Summary
- High-speed differential output architecture designed for demanding signal processing applications
- Voltage feedback topology optimized for wide bandwidth and fast transient response
- Low input voltage noise density suitable for precision signal chain requirements
Applications
- Video buffering and distribution systems
- High-speed data acquisition front-ends
- RF signal conditioning circuits
Procurement Notes
Verify the specific suffix against manufacturer documentation to confirm package type and RoHS compliance status. Ensure the ordering part number matches the required tape-and-reel quantity or cut-tape availability. Cross-reference the datasheet revision date to confirm pinout and electrical parameter consistency before finalizing procurement orders.
Selection Notes
Select this component when a single-channel op amp with differential output and high slew rate is required. Compare the 370 MHz bandwidth against system signal frequency requirements. Evaluate the 11.5 mA supply current against power budget constraints. Consider the VSSOP-8 package dimensions for PCB layout compatibility.
Part Context
This device belongs to the LMH6551 family of high-speed operational amplifiers from Texas Instruments. It is distinct from the LMH6550 series, which offers higher bandwidth but different power characteristics. The MMX suffix typically denotes a specific tape-and-reel packaging variant within the broader LMH6551 product line.
Replacement Considerations
Direct replacement options include the LMH6551MAX/NOPB for SOIC package variants. Verify pin compatibility and thermal performance when substituting between VSSOP and SOIC packages.
